Hello, So I just had to join this forum because I briefly read every bodies post and everybody was helpful!
Ok So heres my situation, I have a 1990 corvette (L98) with a 700R4 Transmission, I have had a few problems already with it, I bought it off a guy in NY, I know im buying somebody else's problem and headache so I took a chance

So I bought it, drove it back home to Jersey, and it was incredible in High RPM on the highway, I had it for about 3 months now and in between that time I had the transmission rebuilt, Installed a 58mm BBK Throttle Body, 44lb fuel injectors, and it came with a ECM from a 96 vette(as ive been told by the owner) and it has a nice Corsa exhaust. Heres my question I had my transmission rebuilt by AAMCO; by me, the technician told me the transmission was modified. I'm assuming a shift kit(he told me he had a drill new holes in the vavle plate), so I just got it back like a week ago and it runs great in 1st and 2nd gear. I noticed my 3-4 isn't as POWERFUL as it once was on the highway but a BIG improvement in my low gears(it turned out my 2nd gear wont shift into 3rd and 4th) and I found out from you guys

So I'm looking to keep it clean and put a couple of bolt ons in it I want to hit atleast 371hp thats my goal, but I did some research and read the L98's aren't meant for Hi-RPM. But I'm not giving up!

Any advice to gain HI-RPM without losing any Low-end torque-and or regain what I once had?(I don't know exactly what I had in it and neither does the owner....go figure) I'm looking into a MSD distributor with "hard-hitting coils". I bought Heldman headers and going to install them soon. Thank you!
