Coppertop Build Thread

[Coppertop8705]

i guess ill let you cho boys in on my super secret monster build thread :wrenchbanana:

the motor is a iron 6.0
Bored .030 over
Callies rods
Mahle -4cc pistons
polished stock crank
arp mains
all new bearings and rings

=)

I think my 228R might be a bit small for the 370 motor. And i could use some guidance one which direction to go. Goal wise i don't have a power number or track time number in mind i just want a fun street car mid to top range cam, and something to work with my PRC heads.

[MrDavid]

Sweet. Did you buy shortblock already assembled or did a machine shop around here do the work?

[NEMESISVETTE]

Nice Granger.. When does it fall in that mota bay? I used those same pistons on my second motor I built for Vette.. Run Diamond pistons now. Is this going to be a nitrous or boost motor.. -4cc pistons is kinda odd for ether.. Keep us posted.

[Coppertop8705]

Because of money I won't be boosted for a long while lol. I'm skirmish of Nitrous still. The motor is already assembled by a ls1 guru bobby admire.

[punisher]

Very nice.

[MrDavid]

So the intent for this engine is to get boosted somewhere along the line in the future? I'd put a cam somewhere in the 232/236 range in it with a 114LSA. What heads you have in mind, and what size cc?

[Coppertop8705]

I don't want to commit to putting a form of boost on it now. So ill just build it to wany I will use it for now. As far as heads that's my weak point unless I get a steal of a deal on some good heads ill be using my prc 2.5 5.3s they are unfilled at 62cc. I plan for 11.5:1 ish compression so I may mill them a bit depending on cam

[PeelerSS]

With those -4cc pistons and some unmilled heads you will not see compression that high.. Not even with aftermarket headgaskets. My TrickFlow heads are filled to 58cc, I run -2cc diamond pistons with Cometic head gaskets at .040 and im not sure my compression is that high.

[Coppertop8705]

How aggressive is your cam? Good ol Google search sent me some numbers awhile back thinking it was close after I milled the heads or used cometics

[MrDavid]

on my 383 setup I had a MS4 cam (.649 lift) and ran PRC stage 2.5 5.3L milled to 59cc. My comp ratio was 12.2-1. I also had diamond -2cc and used a .052 cometic

[01BlackBird]

the engine i have with -2cc diamond pistons and 59cc heads with the custom grind cam is at 12.1-1

[NEMESISVETTE]

Your guys GUESS's are way OFF.. Use a real calculater and dont guess. My compression with TrickFlow heads filled to 58cc, -2cc diamond pistons with Cometic head gaskets at .040 is 11.5028.1 ..

Here is a real compression Calculator..STOP GUESSING

[NEMESISVETTE]

With a 4 inch stroke yes yours would be 12.1, but grangers 370 cubic inch motor (more specificly its a 364) is using a 3.622 stroke with -4cc pistons.. Thats the difference Son.

With the specs stated above, your compression will be in the 10.8 range.

[MrDavid]

Who was guessing other than Granger?


And Granger, you should ditch that LS1 valley cover for a LS6.

[Coppertop8705]

Hmm I must be doing it wrong but with a .040 gasket I got 11.2:1.

[Coppertop8705]

Oh that's a whole nother monster for some reason someone deleted the pcv system on my car so I need to get a whole new one and plan to use a small catch can

Larger bore will increase compression honky, not the stroke.

[Green to da Bean]

That compression calculator sucks, lol. Doesnt even ask for how much in/out of the hole the piston is. Everybody knows the LS1 pistons come up out of the bore.

[Coppertop8705]

I have a question say I want to mill my heads to 59cc is there an equation to say that will be to shave off say .020 or .0xx amount?

[Coppertop8705]

It says to add it with gasket thickness how much would that account for

[Green to da Bean]

I've been told/seen where .008 is close to 1 cc.

[Green to da Bean]

Hell didnt see that. The one's i've seen are .007-.008 out of the hole iirc. Dont quote me on that, just goin by ever shortening memory.:blah blah:

[Coppertop8705]

Hehe subtracting .007 from the head gasket and 58 cc heads I got 12:1 compression. Feisty

[MrDavid]

I'd let the machine shop worry about that. Don't pick a mom and pop machine shop though.

[Coppertop8705]

I don't know any machine shops. Except the napa on laurens they usually do lots of my little stuff

[01BlackBird]

under pressure performance in spartanburg is good machine shop. he does alot of lsx motors. the guys name is darrel

[Napalm331]

1) .7854 x bore x bore x stroke = cubic inches
2) Cubic inches x 16.39 = cubic centimeters (cc's)


CC's of 1 cylinder = P1
CC's of piston in/out = P2
CC's of head chamber = P3
CC's of gasket = P4
CC's of piston dome/dish = P5


(P1+P2+P3+P4+P5)

i used Dover Cylinder to fix my heads. great work and reasonably priced. there right outside of DT Gville.

lil' mexico i would say...lol

[trophystock]

Increasing bore increases compression. Increasing stroke also increases compression. Decide how much compression you want, what head gasket you will be using and that will tell you how many CCs the head chamber needs to be. Have your heads CC'ed to determine what they actually are then shave them accordingly. Compression is your friend run as much as you can.

[SlowOhFoh]

And buy my injectors so you can run e85

i have a turbo kit for sale... its only a 60-1 but u can upgrade the turbo very easy.... 2500 and ill let u have it

[Coppertop8705]

Way outta my budget. I have no problem making my own turbo kit just would have to buy a turbo and valves

[Diggler]

LOL. If there ever was a thread about budget FI.

[Coppertop8705]

Ya I believe those are the few things I cant make. I could mill up all the flanges I need have plenty of tubing laying around. And i think I've got an inter cooler core some where would have to weld up some end tanks.

I'm a machinists at my job. I just don't see how they charge so much for hot side and cold side piping and all that jive. It would take me awhile to make something look good but I have all the tools and materials I think I could knock something out

[98z-28camaro]

BOV, Wasetgate oil lines, tapping oil pan.... tapping the block off plate... its a lot of work... its not hard... just time consuming

[91SILVERFOX]

decent little calculator linked below and like charles said more compression the better and if you put it on e85 like you should i would be all over 12.5:1 easy maybe closer to 13:1 its good fuel. more compression more bottom end torque and the horse power curve doesn't look so bad either

http://www.rbracing-rsr.com/compstaticcalc.html

[91SILVERFOX]

and that 60 mm turbo is way to small you would need two of those on a 370 cid it would run out of steam around 5 grand if it made it that far.

[Coppertop8705]

Anyone have an opinion on a futral f15 cam I found a guy on tech wanting to trade for my 228r.


FMS Custom Grind Camshaft - 236"/239" .600"/.611" 111LSA - aggressive profile with a 3200-7200 RPM range, rough idle

I run a Futral cam.. F14 here. I personally love it.. Do some research on how Futral grinds there cams.. There not like the generic cams that are spit out using a comp cam core.. Futral uses CamMotion to grind theres.

[Coppertop8705]

Guess that means the car is currently unavailable also.....

[Coppertop8705]

Yup cam is here and she is misty feisty

[crumbie]

donkey *****?

[Coppertop8705]

Nope :) donkey **** are for big egos if I wanted vtec I would have gotten a Honda

[SlowOhFoh]

nah, he just got one that needs a set of stock coil springs from a v6 firebird in the heads.

[WhiteIrocZ]

You traded a truck cam for a donkey **** cam, good work ginger!!!

[Coppertop8705]

:secret:

[Diggler]

i have a 233/239 cam in my LS1 car and at this point i would rather have a 228.

going to start tearing down the old motor once i get back from vacation and building up the new =)

[WhiteIrocZ]

PM me the price for the 228r Granger.

[Nauty99SS]

cooking the cam on that Jenn Air will not make it slide in the block any easier .. lol

pre heated for her pleasure. if i didn't know it was my stove i would say its a big boom box

[Coppertop8705]

got the old motor out. tomorrow or this week i shall dissasemble the motor and start putting together the new one

He looks like a mad scientist lol. About. Freaking. Time!!!

[Coppertop8705]

im excited, i really wanna clean up the engine bay some, and i can finally track down a small leak in the power steering

[89RABIDFOX]

Good deal man. I know how it feels to wait for something like that. Sucks. But pays off in the end.

[KUTTER]

its ALIVE - ITS ALIIIIIIIIVE

That thing still leaking. Lol. It been like that for like 4 years.

Whats the state of the replacement MottA?

[Coppertop8705]

short block status awaiting me to bring my heads cam oil pump oil pan and what not and put it all together. valve springs are onw. i hope they are here by friday so i can have the new motor built by monday
