Hey guys.

What do you think of this combo:

383" with around 11.8-12.2 SCR, TEA 200 CNC ported heads, 242/248 SR comp cam with just over .600 lift with 1.6 RR and 112 LSA (ground straight up), 58mm TB and 42lb injectors, McLeod Street Twin with alum. flywheel. Car has 75-175 nitrous kit.

Rest of mods are basically full boltons, car has LTs, ORY, EWP, MSD 6AL w/MSD opti, etc. Still need a good fuel pump

Car has 4.10 gears, but when I go 9" I can change that.

Looking for HOT street and some strip. Gonna be a driver, but I do have other vehicles.

I have this cam in my '88 in a 383 with vic. jr. heads and 11:1 SCR, when I was running it the exhaust I had sucked but regardless the car pulled good. Loves RPM. This is an lt1 grind cam I just used in that 383 at the time. Going bigger SR in that motor.

I would like to use this cam, but, I have no problem buying a new one if its not suited for my application.

I want a tame enough car I can drive around town and on highway w/o too much grief. I think this combo/cam would love nitrous and really come alive on a 150 shot.

With 750 double pumper in that '88 it drives just great around town.

What do you guys think, honest 400rwhp+ possible out of this combo N/A with T56?

Thanks.

P.S. here is the link for the heads http://www.totalengineairflow.com/pr...gmhead/tfslt1/

 

I dont think you should have any problems making over 400 at the wheels.

 

Ya I am trying to debate a SR or HR, or just leaving it stock for the hopes of a good running car.

Def. like the way that SR spins tho

 

Is the car a daily?, if not and you want the most out of your setup I say go SR. Theres alot of power to be made with a SR setup. Go for it man.

 

you are most likely going to want to beef up the t56 a little bit....

that street twin likes to tear up trannies (ask me how I know) and you're looking at a decent amount of power

 

Well the car is not a daily as per say. I'd like to drive it in the city, but its not something i depend on.

I'm no stranger to busting manual trannies.... Can't win when it comes to making power and stock parts.

 

Not a bad combo but I think you could use more head. I know TEA offers a more aggressive head than 200 cc's. I have a set of TEA TFS 220's on my 355 SR.

As for SR or HR? If its a street car I vote HR. Easier to maintain and wont break because of excessive idling.

If its a 90%-95% track car go SR. If you plan on any excessive idle time then stick with HR.

 

We could all use more head..... Sorry ha had to

 

yeah I kinda left that one open for a free shot didn't I? lol

 

i wana hear a sound clip of it

 

good points for consideration.

 

I'd love more head, but the wife is part time when it comes to that.

Says on their website that the 4.030 bore kills the flow on the 220cnc heads. So I don't know if it would be any advantage upgrading to the bigger head.

As for SR, I dunno. I am worried about idle time. But at the same time I really like how that SR acts in my other 383. Above 6k its so clean and rev happy, lol.

 

You sound like you have your mind made up.

 

Ya I want more head

 

Whatever you do, don't skimp on the lifters. I have a 396 SR with Isky Red Zones. They weren't cheap, but they were made for street use w/ the extra oiling holes for the roller bearings. Problem is you will loose oil pressure and it will be noticeable if you use a standard volume oil pump.
This is the problem I'm going through right now. I have some Smith Brothers custom chromoly 5/16 oil restricting pushrods (6.150 in length/ .083 wall) where the oiling hole is half the size (.040) of standard which will hopefully bring my pressure back up. It's okay now, but is too close to that 10psi/1000rpm rule of thumb for my comfort. Hopefully I'll be getting these things in the engine w/in the next couple of weeks and finally get to the dyno for a tune.
As far as hp... I've read where people are making anywhere from 450 to 470rwhp with over 400ft lbs of torque and running in the range of the 11's between the low to high 120's...
