Just thinkin'....
My car is a pretty much stock 302 J-code with stock manifolds, dual exhaust, 10.1 compression, T5, 3.4 rear end with an Edelbrock 1406 carb. It puts out max 230HP @the flywheel and ~195HP (dyno'ed) to the wheels. I get just over 20mpg w/80% highway driving and "grandma'ing it" when accelerating on the 20% of street driving.
What I'd like to do is get 300HP max HP at the wheels but still get the 20+ mpg with the 80% highway driving profile. I'm thinking:
(1) Adding EFI (FiTech) will get me ~10% to 15% kicker in MPG. This is roughly what I saw previously when I put on (and subsequently took off) aftermarket EFI.
(2) Tri-y headers replacing stock manifolds should get me some free HP at the same MPG
(3) Adding a top-end Edelbrock kit such as 2027...
"E-Street for 289-302 S/B Ford (1981 & earlier) - 321 hp & 337 ft-lbs.
Performance results obtained on a 302 Ford short block with 9.1:1 compression."

Clearly this will add performance but reduce economy.
The goal really is more spirited driving not necessarily speed...
The German/engineer in me is wanting to get to 300HP/20MPG w/EFI. The Scot in me wants this to be as cheap... er frugal... as possible... :wink:
Just a "what-if" experiment at this point... but I was wondering whether you guys thought it was possible to do 300HP/20MPG on the setup I already have plus the mods described. Or how would you suggest I go about doing this?
Note: I'm really not planning to do this anytime soon... just like thinking about it... and I do enjoy that the "thinking about it" is *free*... :grin:
