I've picked up a 99 Suburban with a bad engine to replace our 95 Blazer. It would be easy to replace the crank, rod, and bearings and put it back on the road with the original 350 but I've had this purple 302 sitting in my barn since '04 waiting to be installed in something. The 302 was originally built for the S10 and had a ZZ4 cam but for Suburbia I need a lower rpm torque peak. After many, many late hours I believe I've accurately modeled enough components to put something together. Here's the configuration:
L31 four bolt main block, L99 crank and 5.97" rods, H631CP pistons at .030" = 306 ci
L31 heads, stock valves and ports, guides machined for over .525" lift and upgraded LT1 springs
9.0:1 compression
14097395 HT383 cam
1.6 rockers
.040" quench
Single roller timing chain
small harmonic balancer
shorty OBX headers
Mercruiser dual plane ceramic coated EFI manifold
Still working on...
Torque converter choices
Exhaust configuration
The simulation shows one of the roundest torque curves I've ever seen.
