Hey I am trying to get my car to ~400 HP to the flywheel (hoping around 350-375 to the wheels)
I have a 1988 Mustang 5.0 engine and I'm putting it in a 68 mustang.
I've read that the 68 is ~300 lbs lighter than an 88.
So far, I am planning on adding:
1) Elgin E-951-P Performance Cam from AM. Comp Cams recommended a similar cam with slightly higher lifter and longer duration, but for $200 more I'll stick with this one.
2) AFR 185cc Heads
3) Tri-Y Headers
I read an article that claimed after cleaning up the engine, adding afr heads, tri-y headers, and upgraded rocker arms that they got the car pushing just over 400 hp to the flywheel. Not sure how accurate it was thought because they claimed after cleaning up the engine and throwing on a single 4 barrel carb manifold they gained ~50 hp or something like that.
I had the engine boiled and the cylinders looked to be in great shape so I didn't have them bored out, only honed. I'm going to use the same pistons and just get a re-ring kit. I'm also going to carbs, I have a dual 4 barrel carb intake manifold from edelbrock that I'm going to use and 2 4 barrel elderbrock carbs. I am also going to go from the c4 auto trans that came with it to a 5-speed manual (IF YOU KNOW WHERE TO BUY ONE CHEAP, PLEASE TELL ME! THANKS ) and I have a 9" posi rear end right now, but I will probably be switching to an 8.8" rear end with ~3.55-3.73 gears.
I want to keep the car streetable. I just want a crazy amount of horsepower without going to super/turbo chargers. I want to be able to keep up with the new 2011+ 5.0 mustangs
Thanks so much guys!

That cam and those heads do not go together. A cam in the 225 duration and 0.500 lift will get you into the 350 flywheel hp area with those heads, assuming the intake ports reasonably match the head ports, which will be a lot of fun in a classic Mustang. The cam you've selected will choke the engine power, but will put out a lot of torque down low, and get decent gas mileage.
89 Coupe, 369 big bore, AFR, custom Comp cam, Kooks, 3" exhaust, 11.6 @ 121 mph
04 Cobra, JLT 12" CAI, Magnaflow, Borla, Stifflers, FTBR Rr Susp, MM Frt Susp, 12.4 @ 115 mph
67 Cougar, XR7 GT, 462 FE, 4 spd, Edelbrock heads, PI intake, Global West
Somebody had vodka for breakfast before they wrote that carcraft article. But with those heads, a better cam and a really good intake like a victor jr. or a trick flow "R" series to let the motor breathe and a good free flowing exhaust with long tube headers I can see you making 360-370 crank HP. My 5.0 made 306WHP with similar parts. Plenty of motor to keep up with a stock coyote at the strip.

Yep, I'd lower your hp goals and exploit your weight advantage. Check my sig, you don't need 400hp to run with the new stuff.
