The down side to a W-9 deal is headers , intake and cooling system.
You need to be creative with two and lucky with the other.
I'd look at a Super Commando / Indybrock / Procomp kind of deal if you need aluminum or a W-2 if not.
10's is awfully ambitious , but not impossible.



Good post!!

Remember Bondo just went 10.57 with the procomps( first outing) at 9.5 compression in a bench seat swinger. I know the 4 inch crank helps, but no more than3 or 4 tenths, with a relatively small head like that .And I wouldn't be at 9.5 compression either. so make up some power on that front.

Local racer( who sometimes posts on here) has a 340 with J heads and a flat tappet(3100 pound Duster) that has been 11.00's a number of times. His heads go I believe 251max. Ran teens at Norwalk. It's been together a few years now.



Sounds like you had your mind made up and nobody is going to tell you any different. Not sure why you asked for input ??

If you can gain 3-4 tenths with a 5-$600 crank...and have it be more streetable...why wouldn't you ??
