What kind of power in LT1's with all bolton's and a cam put down? What do these kind of cars run in the 1/4 and 1/8?

 

It depends on the cam a lot. If you have one of the "bigger" cams (like the CC306), you are probably looking at about 360rwhp (stock heads + all bolt ons + tuning). With the smaller cams (like the Hotcam and the CC305), probably around 330rwhp (again, stock heads + bolt ons + tuning). Actually, a search on this topic would help you a lot. You could see what people actually put down with different cams.

 

See #'s in sig, all the usual boltons and a relatively small cam.

Youre getting 400whp out of a GTP??? Wow, I had no idea they could make that much power, that's sweet.

 

316 with a hot cam and AS&Ms with pcmforless. If I had LTs with an ORP, 330 would've been forseeable but I need emissions.

I think a CC306 at 360 is a very high number ??

 

See sig for dyno numbers and track times. This is with a relatively small cam, stock heads and no tuning.

 

You might want to shorten your sig a bit, the admins here don't like the mega-sigs too much

 

Numbers with a 230/236-112 and ported heads in the sig.

 

So how long will your gear box last?Thats the question.

 

hey llafro, does that 58mm TB actually work good with your setup? I heard anything over the 52mm TB on an NA motor was basically useless. Maybe I heard wrong?

 

Damn maybe i should have gotten a gtp instead of my z28. Nice #'s. How much money have you put in that thing. Also what times are you running?

 

I thinkOne of the guys here, Marcin, I think his nick is "xxsaint69x" or something like that (sorry if I messed it up), got like 363rwhp from a cc306 with stock heads. I might be wrong though, correct me if I am.

 

i would say between 315-330 with a small cam (LT4 hotcam-305 cam) to 350-375 with cc306 or 230/236 cam with stock heads

i have seen stock heads/cam only LT1's run low 12's. i plan on doing this too as as soon as i get my 60's down!!!

 

Hey Blown Six why are you curious about a cammed Lt1?

Nice numbers there, one day I hope I get my GTP to that level. I will have to stick with the Z for now though. I hate to start tearing apart a new motor for heads and a cam and all that. But, it won't always be new

If you are getting ready to race a cammed LT1, put on the little pulley and do your thing.

If your thinking of getting an LT1 and doing a little work to it, I highly recommend the combination.

Do a search on here for cams and you should get all kinds of info. for the track and hp numbers.

 

Next chance you get check out the High performance Pontiac Mag on the rack....It has one GTP running Low 11's

 

I have about $4000 in the motor. My gtp ran 8.46@83.66mph 1/8 1.94 60' before I did VS Cam, ZZP Stage 4 M90, 2.6"/2.7"/2.8"/3" ZZP Modular Pulley system, DHP PCM, ZZP Stage 2 Intercooler, INTENSE 9.5:1 cr Forged Pistons, ZZP LS1 tb & 85mm LS6 maf, 42.5 lbs Flow matched Lucas Injectors , 3" Exhaust into 2&1/4 y, SLP headers, INTENSE Trans 2.93 gears, Nitto 555R's 245/50/16. I ran the 8.46 with just about $1100 in mods. I think if I can pull off some 1.6-1.7 60' I would guess I would be running 7.5-7.4@93-94mph 1/8 11.6-11.4@116-118mph 1/4, keep in mind this is with stock 2.93 gears and stock stall.
