I'm planning a winter ugrade to my Ranchero and need some direction from my opinionated brethren......
What I got is a '63 Ranchero with a 289 / 4 Speed and 3.20 gears in the stock 8" rear. The engine is a .040" over 289 with stock pistons and stock heads. A Crane Energizer H278 H10 cam, Edelbrock Performer 289 intake and a small Carter. I think it's about 500 cfm.
The plan is to keep the bottom end as is and focus on getting it to breathe better. I have a line on a set of mildly ported stock heads with bigger valves and roller rockers. Not sure how big but bigger. A Performer RPM to replace the 2121 in there now and re-jet the Carter. Finally, exhaust. I'm expelling gasses through stock manifolds and a 2 1/4" system with glass packs and an H pipe. I don't wat to go long tube headers so do I go HiPo 289 manifolds or a set of shorty's? What is the best bang for a thin wallet?
Come on, let's here it!!
