Alright everyone. After 14 years, I wanted to bring this thread to a soft close with an overview and driving video I just posted here
Since starting this thread, I've been to college, gotten married, bought a house, and switched jobs and over the past couple of years, I finally had the time and money to finish this build up.
Below is a list of the details that I go over most of in the video Original Chevy 250 block inline 6 bored .040" over .040" over Ross racing forged pistons 1.94" intake/1.7" exhaust head with lump ports and 7/16"? studs done by @tlowe Compression ratio calculated to be 9.27:1. Comp cam roller rockers Stock Rods with ARP rod bolts Stock crank and crank bolts Offenhauser 4BBL manifold SPA Turbo Manifold GTX 3582R Gen II ball bearing turbo running at 13psi (water cooled) Holly Super Sniper 650 Go EFI replacement fuel tank with 340lph in-tank fuel pump Generic eBay intercooler hydraulic flat tappet turbo Cam (cam card in video) high flow water pump Tial MVS 44mm waste gate 3" exhaust to straight through borla muffler Standard HEI distributor modified for timing control by Holley super sniper (shown in video)
I can't thank y'all enough for all your help along the way. I'll probably be pushing the limits here and there hoping everything stays together. I have a complete spare 230 and spare 250 just in case anything goes wrong because this car will never see a V8. I'll post here if there are any major developments but as of now, I'm happy with the power levels (I'm guessing low to mid 400HP?) and it'll spin the tires in first and sometimes second gear on my 255/70R15 tires which are quite tall. 0-60 I'm guessing in the mid to low 5 seconds but a column shifted manual doesn't help much in that regard.
69 Buick Special Deluxe. Intercooled Turbo Chevy 250 @ 15psi on a stock long block. It's kinda fast.
