383 Stroker up date
I found a guy I can trust to build and install my 383 stroker in my 91. He has a Monte Carlo he built running low 11s . I'm sure it will be a money pit before it is over. He started talking about headers and scraping the pollution junk. As long as it runs ok and no codes it's ok with me. Way too much junk hanging on the block. He thinks it will be on the road by December. Just in time to drive it 200 miles south to Iowa for winter storage. Wife can keep her Terminator. All she will see going to Iowa is Corvette tail lights. Can't wait! HP is like a side arm, just because you have it don't mean you have to use it. It is reassuring to know it is there when you do need it.

Getting rid of pollution controls wont add much in the way of power but will clean up your engine compartment a bit. Personally Id lieave theEGR in working order. Youll love the extra torque from that stroker.

What kind of specs is he going to build it to?
Are you going to stay with TPI?

Why leave the egr? Does it help cool the burn or something? I thought it took away octane (makes mix burn hotter).

Probably for emissions, though I've never heard of the EGR making much difference for emissions.
Are you going to go with a hogged out TPI? The stock TPI would absolutely be a waste on top of the 383, IMO.

want to
The builder wants to do a bunch of stuff to it. I don't need 500 hp. Have to draw the line some place on $$$. Headers are out for me, new intake and runners pushing $1000. for how much gain. It is mostly a trade off at some point. hp verses bucks. Compression and cubic inch is the best bang for the buck then you have to look at the real gains. Will it give you codes or running problems. You can bore darn near to water but how hot will it run and how long? Then who can work on it after the job is over. Good wrench boys go by the GM book and won't know what to do with it except put all new part back on you just took off. The builder has some good ideas I will probably go with. Thanks for the input.

Don't waste your money on a 52/58MM tb.
I had a 406 superram and went from a stock 48mm to a 58mm and i gained nothing but a $430 hole in my pocket.
I have a 48mm TB on my LT1 running 117MPH in the 1/4mile.

If I were you I would not let the guy build you a L98 to run with 11:1 compression ratio. If its an LTx engine you can get away with it, but not with a L98 engine. Especially if you do away with the EGR, that alone will cause detonation. A EGR valve when it recirculates exhaust gases into the combustion chamber it will cool the chamber to deter an heat related issues that will cause detonation.
