Need help with 390 stroker build
#31
with edelbrock heads, flat top forged pistons and forged rods, buying a new 390 crank shaft and headers, intake and Cam I'm looking at about 4500 roughly and will be seeing 10.5 compression and 450-500 hp

It gets into your blood. More power,,, More power...
You could have Keith Craft Racing port your Edelbrock heads and intake to match, so when you step up in power, your heads, springs, valves, and intake are ready to make good power.
We went with a single plane Victor intake, but I am not sure that maybe a dual plane intake might make more torque and just about the same hp. Might be worth checking into before buying the intake.

what else did you have in yours? I'm running a 360 thats at the machine shop now... It will have a 390 crank, bored between .30 and .40 over block decked to zero, between 9/1 and 10/1 compression, Performance cam, rpm intake, gasket matched stock heads, holly 650 and headers and no clue what mine will make hp wise.... Everyone was saying only about 300hp and no clue about torque

Once you see 600 then you won't be satisfied until you make 700 then maybe 800. If we put nitrous on ours, we should see 1017 hp. or 967 hp with a 200 hp shot of nitrous.

I'm about $12k on my 445. Heads, rotating assembly, machine work, cam, rockers, new balancer, fly wheel resurfacing, new clutch, fasteners, carb, intake, fluids, etc. It adds up.
Once you decide to build a stroked 10.5 to 1 compression engine you are into the 500/500 zone and you can't help yourself.

I dunno, there are lots of factors in there.
Aside from the machine shop work, I did my build. I spent a few years scrounging parts and did mine for under $10k. (and I've got one more carburetor than your build YellowTruck)

thats awesome, on my thread people were saying only about 300 hp with my set up

500 plus hp is not hard to do. Our last engine before our 511ci was a 428cj that put out 530hp on the dyno. It was fairly mild. 10:1 compression, Edelbrock intake and heads, mild porting, 800cfm Holley carb. headers, flat tappet cam with .625 lift. with off the shelf parts.
You should be able to build a 390ci engine putting out 400 hp fairly easy.
It's been a lot of years since I built a mostly stock 390 engine, but the last one I built for my brothers truck made over 400 hp.
