Getting ready to rebuild the 350 for my '89 K1500 ECLB,
I've got a few options and I'm trying to figure out what head combo to go with..
I want a decent amount of power (300-350hp) respectable MPG, and super reliability.
-I've got an .030 over kit wit stock style dished hypereutectic pistons, H/V oil pump, and a Comp #12-388-4 252/262 adv duration .425/.440 lift (PC and TBI safe).
- Hedman LT headers, 3" header back w/ h-pipe duals w/ 2x series 70 flowmasters.
For heads I dunno if I should do a;
- "performance rebuild" on the stockers
- a set of new Hi-Po 305 heads off a marine engine, 0hrs on them. With the dished pistons, I should maintain a decent comp. ration of 9.0/9.5-1 keeping it 89 pump gas friendly.
Has anyone tried done this kinda combo of a 350 with 305 heads?
