Stock bottom end LT1 with a home ported set of stock heads, and cam.
440 RWHP LT1

 

that is awesome, i wonder what cam he has...very interested in doing a cam swap here pretty soon.

 

A Thunder Cam, of course.

 

whats even more impressive to me is that it made 395 vertor unlocked,exhaust capped,and belted thats a mean lil LT1 car there

 

I just recently did a stock bottom lt1 heads/and in house custom grind cam and put down 452rwhp/399 torque

 

I'm impressed he made that much through an auto

 

SAR2K stealing Tim's screen name:
Joe I thought that car had worked AFR LT4 195s?
I'm running ported factory LT1 heads with 1.94/1.50 valves.
Anyway congrats on the 452, damn good #'s. Hopefully with a little more tweaking I'll be hitting 460 soon.
Steve...

 

what is the general size on these cams? are they streetable at all? solid roller, solid tappet, hydraulic roller, etc.?

 

The cam that we used is a Hydraulic roller. Streetability is a personal opinion but yes it's streetable for the most part other then a lumppy idle, although at 1000rpms it idles in park and in gear quite nicely. The compression is pretty low on this motor so it would run on 91-93 pump gas with NO problems. As Steve said earlier the fuel that we dynoed with was 6 month old 93.

 

Thanks ,Yes they were reworked 195's, but as most have found out lt1 casting's isnt but maybe 5 cfm difference under .500 lift in the right hands...his 195's peaked at 279 cfm not alot of air considering...but on the other hand I ran 10.94@124 mph 3 years ago and my heads only flowed 255 cfm peak ...In the real world as you can see peak flow or head type doesnt really mean alot...good port velocity and flow volume off the seat to .500 is where its at and a stock lt1 casting rocks in that area when ported correctly with a relatively small runner...

Cam I designed for that setup was a hyd. roller under 240 dur. @.050 and less than .600 lift and he drives it daily.To bad its a convertible

 

On a side note congrats on the 440 rwhp not bad but that torque curve could been better...Hp is cool but, Torque wins races

 

nice setup Joe. Im looking for a new cam for my setup and will be going as far as i can while still maintaining streetability and a close to stock bottom end...just trying to get an idea on a large cam that will create good power with ported heads, intake, and every bolt on possible(only 2 bolts-ons left for me). I was hoping for around 410 rwhp, if not, then im going stroker

PS Nice to see so many strong running LT1's, havent heard much about LT1's in a while.

 

Theres some of still kicking ...Friend of mine Chris Jones just the other week at a eastern f-body shootout ran 11.19@121 with stock bottom end lt4 heads and custom hyd. cam..he never had it on the dyno yet but I'd say it putting right much down to run that number.. he was right on the heels of cam/heads ls1's within a 1/10..

 

any track times?

 

The car should be going to the track on Oct. 26. Until then feel free to call her a dyno queen.

 

aint that a bitch, i spend 2100 on a head and cam kit and only put down 390 and 356 torque... i only could manage a 11.9 out of it.

 

So what's the secret here? Is there one? These aren't readically different combos from what has been done in past years. Yet the HP numbers from the h/c lt1's have jumped 30-50hp.

 

Oh please tell me how so! I have AFR LT4 195cc and a 224/236 560/560 on a 115 (blower cam) and I only mananged 409RWHP! If I can get 452 i wouldnt definitely ditch the blower in favor of NA!!

 

Ditch the blower ste up for na? A well built LT1 with a blower can make mid 500s to the wheels if its set up right. Seen far to many do so. I want to build up a forced induction car one day.

 

Wow, lots of nice setups here. I have to get my blown setup onto a dyno after I do some work, hopefully I'll be putting down a little over 400 on stock heads without an aftercooler. Once it's aftercooler and has heads, a pulley swap will take place, and I hope to break 500. Good luck to everybody's setups.

needforspd, are you running stock heads or an aftercooler?
