I have a 01 camaro z28 A4 car. Following mods are

slp lid
kn filter
bo white TB
bbk Lt's and matching y pipe.
3" single exhaust through a magnaflow
3500 ptc converter
Shift kit

the car has a burnt exhaust valve. No tune! And I am not very light myself. Race weight right now is #3680

I want to know what heads/cam will take me into the 10's 1/4 and 6's 1/8th.

Right now the car has ran a 7.87 the way it sits with only those mods.

Depends where you race and location

UD pulley
Fast 102 with 92MM TB
Ported AFR 215s/TFS/AI 243/799 226s milled(If you go AI route you will need to know your camshaft choice first so they can mill it without worrying about piston to valve clearance.)
Tons of cams with those heads can get close or at it if your trans can get take it-you will have to shop around and talk to the sponsors since you are running a tad small converter. MS3,Raptor,EPS grinds etc can do it...
You will need more gear and some drag radials at the very least. Only things against you will be the weight of the car and lack of converter.

PM Deerslayinrednek.
His car is as heavy as yours and has gone 10.8s at 123 in good air on the east coast. I think he has more converter than you though

I plan to try and get the race weight down about 300#'s. texas speed told me that with a aggressive cam I would need a larger stall and some steeper gears! I am looking at patriot performance stage 3 243 heads with 227 runners. 2.08/1.60 valves. ls6 intake and a ms4 cam. And possibly alot of suspension components if I have traction issues.

I am not sure if the MS4 will clear stock pistons with that head. Id work on getting the power and then work on traction. With an auto,more gear and more stall you might not need as much suspension work as you think if car is at 3000 pounds.

BIGDATOWN

Did not think about PTV. BUT I am pulling the motor when I do all this just to freshen up the motor before next season. So if fly cutting the pistons is needed then thats what I will do. If a ms4 will be better suited to my goals that is!

BIGDATOWN

Ok so I reread and compared the ms3 to the ms4 and TSP reccomends the ms3 with stock CI motors. So I guess the ms3 it will be!

why do you want a 2.08 valve on a stock bore?

BIGDATOWN

Its just what they put in the heads. Def wasnt a request on my part lol

Have you looked at the bronze guides aspect and figured in full roller rockers?

The heads are cheap and that is their draw, but ask yourself how can one company charge nearly $1000 for what is very good CNC work that consistently delivers great results and then another can charge barely any more with new valves, new guides and supplied cores????

Then their ad even suggests 4.00" and larger bores for it.

Settle down and look for results you want to follow and look at what that person did to get there. You wont get there by buying the cheapest head you can find with the biggest valve.

BIGDATOWN

I thought a ls1 motor was a 4.00" bore motor? But I understand what your saying here. Can you elaborate on the bronze guides and why i would have to run roller rockers instead of stock rockers?

You will need to flycut for sure.

look at a vengeance racing head/cam combo,or a TSP combo.get the best head you can afford and get a custom cam.

there is no best head and cam.. Its all combo..combo..combo..

Spellbound

In my girlfriend's car, at that race weight, it took four hundred and twenty seven cubic inches topped off with TFS 235's and a 4500 stall to run tens.
Find a couple people on here that's done it with stock cubes and follow their recipe.

Stage 3 heads won't work on a stock cubed motor. Get ready to buy ALOT of suspention and a 12 bolt to stick them steeper gears in.

I know its not 10s, but the old car in my sig had hand ported stock heads, B1 cam, LS6 intake, mac mid length headers, ory, mufflex catback, ud pulley, free mods and a PT4400 Yank. Suspension was Hal adjustables in the front, lakewood 3 way shocks rear, sfc and lower control arms. ET streets out back and skinnies on the front. Car was mail order tuned in 2001. So certainly not tuned by todays standards. Race weight was 3450.

Like was said before, there is no best head/cam it is the combo. There are stock internal guys running faster than I did, so it definately has a lot to do with how well the car works at the track. Be it weight, suspension or whatever. There is a lot more to running 10s than just the power.

The 6.0l engines are 4.00" bore the LS1 and LS6 are 3.898 bore stock(edited).

Bronze guides do not cope well with the side load stock rockers place on the guide and you will wear the guides out. Stock rockers are good with a trunnion upgrade but are best run with stock style PM guides.

ls1/6 are 3.898 bore stock

Get a bigger converter. 4000 is a good flash point.
