Did you use Custom Pistons? Your bore would be 3.970 correct?

Mine was offset bored to 4.0 so an off the shelf stroker piston would work.
 
WOW! What a bad a@@ maternal fornicator! LOL :toothy10:

Don't know I spin a little off the line but not much. I don't have any slicks to try.

Off the self pistons they are in KB catalog page 21. Bore size is 3.97 I think it makes my total cubes to 396
 
wow!I love the sound of that cam and the way it idles!:cheers:
What kind of mods to the heads and valves are needed for a cam like that?

Ok, so the ones based on the 390 kit............Cool! Those are forged right?
 
Sounds great! I am wondering how these 318 strokers compare to the 360 stroker kits that are out there? Running on pump gas of course. Have you had the engine dyno'd?

I am going to have mine dyno'd at Brian's Shop before I install it. It is only a 10.20:1 Pump Gas Motor. I had my 410 that is in my 70 Dart Dyno'd at Brians, I am glad I did. I had major oil leaks from the valve covers. It would have been a MESS with it installed in the car to get cleaned up. After 5 min on the dyno BOTH gaskets just started Pouring out oil all over the place.
 
Nice thread, I want to do a 318 stroker also. So all the info from you and others on this is greatly appreciated! I had a '71 318 that I back yard rebuilt that had the heads milled down .030. I put a holley 650 on it with an eddy manifold. Thats all. I was such a noob I could not for the life of me understand why the 4 barrel never opened! LOL. I had a chance then to do a lot more with that car.........Anyway, like the thread. Thanks all!
 
Ummmm, that's not a Torker II on the engine in the vid. Change it out???? Looks like a Victor.

12.20 in the 1/4 with what ya got isn't bad! More stall and some slicks...Muha ha ha ha ha

Whatcha got for rear suspension?
 
Sounds a lot like the motor I'm building right now, cept mines a 67 date code block, same exact pistons, rhs heads, solid cam, scat rotating assembly, m1 intake with 950cfm carb, and fender well headers with 1 3/4 primaries and 3in collectors.

Having the same cubes as a Chevy bb from a 318 is a laughable subject..:toothy10:

Almost forgot, she runs on e85.
 
And if they want proof, it says so on the side of the block.. haha
