How much hp???
Hey ratsmoker or anyone with a computer dyno, can you tell me about how much horsepower I will have after this rebuild on a <a href="http://www.motorhaven.com/">390 </a>conversion? Here is what I have done to the engine:
<a href="http://www.motorhaven.com/">390 </a>crank C1ae with c7ae-b rods
Bored .030 with H304p's should be about 9.5:1
Standard heads c8ae-h (about 70 cc ) rebuilt but not ported
Melling cam .514 lift Intake/exhaust with 310 dur (224 at .050)
True roller timing chain and comp cam roller tip rockers
Edelbrock performer <a href="http://www.motorhaven.com/">390 </a>intake
<a href="http://www.motorhaven.com/">Holley</a> 670 street avenger
Electronic Ignition pertronics set up and Msd Ignitor box
C6 tranny with shift kit and Daaco 2500 stall
Aluminum driveshaft( no carrier bearing anymore)
3.5:1 9" (still open)
Anyone know what this is putting out?? This is going in my 69 f100.

If you mean the separation on the cam lobes I believe it was 110 degrees but I dont have the cam card handy(across town with truck) Otherwise make a guess, your guess would be much better than anyone I would give.

Ok, I found the specs for the camshaft RS,

Adv Dur 307
Valve lift In/ ex .514
Center line Int 110 Ex 114
Cam lift In/ex .292
Rocker ratio 1.76
The melling part number is 24218 class II cam power range is 2200-5700 need a stall atleast 2200. Also I will be running headers.
