Howdy all. I've been dabbling with the idea of pulling the old LO5 from my 1994 Blazer. This motor has served me very well for 27 years. It has 156k on it. For all 27 years this truck has had no business in the passing lane. now that everything on the road is about 300hp the situation is worse than ever. I've pretty much ruled out an LS swap. I'd like to stick with period correct architecture. Ideally, I even want it to look stock. So, my thoughts for 300-350 gross hp are:
- 4 bolt small block set up for roller cams
- cylinders heads that actually breath WITH HEAT CROSSOVER
-LT1 or LT4 cam?
- preferably stock intake but would do an Edelbrock TBI if necessary
-SPR Performance TBI modification if necessary
-Tuning....no idea who to talk to about this. EBL Flash II looks interesting...I've done some of this work with EFI Live on a Duramax, though I have less spare time these days.
My goal is about 300-350 gross HP revving out to 5500ish
The reason I'm posting this is because I'm wondering if anyone here has set out with similar goals. If yes, which parts did you select, and what was your experience? I'm not trying to build a monster, just more usable power in small block format, with stock underhood appearance, utilization of factory fuel lines, wire harness, and computer.
