Re: Eliminating Engine HP Loss
If anything get an aluminum water pump and a mini starter to drop some weight. Aluminum heads and one of those fancy aluminum holleys will drop weight. I've had my power steering off for a while and daily drove it like that just fine.
Less weight is like having more hp. General rule is 100lbs is about equal to gaining 10hp = to 1/10th in the 1/4 mile...theoretically although losing weight up front will help launch so your getting double benefits.
The later 80s trucks have aluminum master cylinders which are 5lbs lighter already.
Also when's the last time you picked up a factory driveshaft? Damn things are like 35lbs a custom aluminum driveshaft is maybe 8lbs. And that will bet you more rwhp just through efficiency. Optimizing your pinion angle is free hp as well
Comp cams also make some nice entry level full roller rockers if you don't already have some. A one inch phenolic tapered carb spacer off eBay is a good hp boost and also a good bang for the buck. I've felt gains with swapping my typical drop base air cleaner to a raduised based with a k&n stubstack.
Also optimizing exhaust. An h pipe will net you gains for pretty cheap if you don't already have one. Setting your timing curve and super tuning your carb with an A/F meter will net HP efficiency as well. Doing all this can very easily net you 50hp gains just through making everything optimized. When you tune at the track (very good idea for data logging) make one change at a time and note the changes.
