Gday,
360 ci, 4.047 x 3.5. 664hp @ 7600 , 529 ftlb @ 5700. Ported 2v cast iron heads, active intake, 1.410 x 1.687 apd methanol carb.
5.78 rod length, 1.2mm ring. 13.12 comp.
Solid flat 272/280 650 net lift 106 sep. Trend tool steel lifters, t and d 1.75 shaft rockers.

3160 lb falcon been 9.81@136.5 in good air but showing lean on data logger, carb is maxed out on booster id.
Hasn't been plain sailing, hurt a lobe due to nitrided camshaft being 15 points rockwell soft.
Currently in process of converting to very similar spec roller and converting to internal balanced crank.
Fuel system has been addressed so should be able to run a bit harder hopefully.
Cheers
Paul

'70 2 bolt
-Badger cast flat tops
-Aussie 2v heads. I only cleaned the rough castings in ports with a Drimal
-Comp 282s cam 282/282 236/236@.050 .570/.570 lift.
-Crane Energizer roller rockers with the Crane roller rocker 7/ 16" conversion kit
-out of box Weiand Xcellerator 2v intake
-650 Speed Demon carb 70/76 jets - made a strait 12.8 afr 1" cheap carb spacer 14" K&N filter
-Used duraspark ditributer -changed springs- MSD box
-Headman 1 5/8 x 3 headers 3" exhaust - 3" H pipe 3" Flowmaster Delta Flow mufflers

I read with these heads and pistons its around 10.25 compression. Dynoed it with the smaller Wolverine hydro cam --- 290/290 .505/.505 and it made 250hp@5800/320@2800 at the wheels . I never dyned it with the Comp 282s solid cam - only raced it. Car at this time was 3345lbs with me in it. Best ET was a 12.75@106 Wallace Racing calculator says at that particular run it was making 320 flywheel hp. I dont know how accurate the old FORD dyno numbers were back in the day but the 1970 2v Cleveland was rated at 250hp/300tq. If thats the case, then I upped the factory power 70hp/80tq with just bolt ons.

All I've ever run are iron heads. They'll have had the pockets cleaned up, but not much more than that.

Current combo;
377 inches. Crower 3.7 stroke steel crank, Oliver billet rods, 13-1 compression. Solid roller, Strip Dominator intake, Ron's injection, powerglide, 2950 lbs raceweight '69 Mustang, no idea on the hp level, but it has gone low 6.20s in the 1/8. Hoping to see some 6 teens out of it this year with a cam change.

Previous combo;
357 inches, stock rods, factory cast crank, HEAVY TRW pistons, OC heads, 11-1 compression, solid flat tappet cam, Strip Domi intake, alchy carb, C4, same Mustang, ran a lot of mid 6.30s in good air.
