Who builds the best small block to run 10.0s in a demon ? I figure 550 to 600 hp would be needed ?
71 Demon

He's clearly forgotten more than I will ever know about these things. I haven't used his machining skills yet , but I have gotten a hand full of parts and some great advice for my deal. I wouldn't hesitate using him for a build if the opportunity presented itself.

I appreciate the kind words. But there are lots of guys who can do same things I do...10.0's out of a SB these days is not that difficult in typical A body.
Depending on vehicle weight & efficiency you'll need to be in the low 600's HP wise to get there in a typical bracket setup. The car has alot to do with the ET. I've had 610 HP motors run in the 9.70's @ 3100 LBS & I've had 675 HP motors off same dyno run 9.80's @ 3200 LBS... you can figure out which chassis setup/coverter etc worked better. HP is'nt everything when it comes to building a quick car.
Thanks for the info, could you do it using a 360/380 hp magnum crate motor with the iron heads ?
Not with the pistons/rods that came in the Crate motor. You probably could for a few passes, but I would'nt build it with those parts.
Last crate motor I worked on had piston to valve clearance issues with a mild hyd roller. That was a 10.60 piece & that was about as far as I'd want to push a 380 crate.
There is a difference between guy in their garage going & taking 360 Crate & slamming some big heads on it & running fast for couple passes & a reputable shop that has to build the thing & make it live for 400+ passes etc & put their reputation on it surviving. Anything that comes through the door with stock rods or Eagle SIR's does not leave my hands without a rod upgrade. I just can't half ass stuff like that, it's not worth the job. But you'll get guys who will tell you, sure, throw a set of W2/5/INDY's on it & a big cam & you'll have a 10.0 piece... But I would'nt do it.
The only part I'd use from the 380 crate for a reliable 10.0 3100+ LB A body would be the 360 block.
Now if your car is 2500 LBS that is whole different story.

Do not mean to hijack but how large of a cam did you put in the 380 hp crate motor before you ran into piston to valve clearance issues. I am thinking of buying ported Edelbrock heads and going larger with my cam on my 380 hp crate motor.It will be in my little D-50 that weights about 2950 with me in it,5.14 gears and 3500 converter. Has gone 7.46@91 mph so far in the 1/8. Thanks!
1.33 60 ft,6.21 at 110.59 in the 1/8, pump gas small block,2950lbs,drag radials,mufflers and driven to track ...

I'll have to dig up the cam card, it was'nt "huge". High 240's/low 250's @ .050" 108 LSA & high .500's low .600's lift if I recall correctly. Made good power, but was real tight on piston to valve.

Thanks for the info Ryan! I hope to get my D-50 in the 6.90's with the head and cam swap.
