Thread: Lt1 383

Tweet

I am assembling a LT1 stroker 383 with forged eagle crank, H beam rods, SRP dished pistons. Have a 58 mm throttle body, lt1/4 hot cam and 1.6 roller rockers. My heads are the new afr 195 street eliminators. Will be using the hooker long tubes. What do you guys think of this for a daily driver and what if anything should I change. What size injectors should I use and what modifications will I need for the ecm. Thanks for reading

The cam seems small for the heads.
I would install a larger cam to work with the heads if you have the comp. ratio to support it.
With that cam I would think the smaller 180 cc AFR head would work better.

already have the heads so theres no return there. My compression is 9.5 to 1

I would look at the Lunati Voodoo cam #60121 or the 60122 if you want to take advantage of those heads.

I had one of these built and put it in a 95 camaro I use to have. If your spending all the money to build the motor I would definately get a bigger cam. Also something that I will tell you is to get the GM optispark. I bought one from accell and it didn't last. For the injectors get the 30# FORD SVO injectors (yes I said ford). A lot of people have had problems with the Accell injectors and the SVO one's work great. Also take the car in to a good tuner in your area. A mail order tune will get it close enough to drive around but if you want to get everything out of it you need to take it to someone. If you have any problems go to http://www.camaroz28.com/ and look through the forums there. This is a common build and a lot of the issues are addressed there. Also another thing you need to think about is what your going to do about your altenator. The original one set on top of the valve cover which had a dent in it. With the bigger rockers you won't be able to use the stock valve covers and you'll either have to get a custom bracket to raise the altenator higher (which looks ugly), move it to the other side of the motor with a special bracket (which squeeks under high torque) or custom fab a set of valve covers.

This is going in my 66 el camino with a 2004r and 308 posi rear gears. As far as the opti I have a new one and changing it on mine is really simple. I didn't even think about the valve covers. I was under the impression that the 1.6 rockers would fit. I will double check that before I install. I already have the 350 LT1 installed and have been driving on a daily basis for over a year. I have 26# injectors on the 350 and it's good to know I only have to go to 30#. The AFR heads have provisions for both the early style and late style valve covers so I think I will be going with the early style just to trick some people up as far as what I have under the hood.The fender emblems still read 327.

Also another thing you'll need to get is that the AFR 195 Heads are raised runner and you'll need an LT4(raised runner) intake for them instead of your original LT1 intake.
