r3 with indy heads

any other ideas on a combo for this can you get of the shelf pistons for 4.200 0r 4.180 bore

Did you get it off Graig Geddes by chance? I know he had one at one stage. He had some 60mm core roller cams he was selling cheap also.
In the pics you sent me, it looks like it has keyway lifter bores, and they don't look like they are in the standard position. I would measure the spacing to be sure. It should be 1.76", but these Comp and PST guys would move things around.
Bore space is going to be around the 4.180"-4.20" mark, with a deck height of around 8.8"-8.9". If you are lucky it's an early engine with 318 mains, otherwise it will have ford 2.25" mains.
The oiling for wet sump will require a few galleries to be drilled, and drain backs added to the lifter valley. Is the bottom of the cam tunnel enclosed?



I have a NIB Comp Cams 60mm Solid Roller, but I doubt it is going to be suited to your combo. Plus you drive that AP6 of yours abit, it would kill too many sets of valve springs!

With any luck Mafo (Ken) chimes in, he has an ex Nickens or Patterson PST engine. Ken is quite helpful.

i got 3 cams and block for 2 slabs craig is a good mate of mine and yes it was his ,if it all works out it will be good i am trying for 420 cubic inchs

I didn't know he still had the block, I remember him telling me in an email that he picked up some Chrysler stuff in a deal he'd done on a car, he tried selling the stuff, but surprise surprise, no one wanted it over here.
I imagine you are going to change the lifter bore bushings? Check the block for cranks, some of that PST stuff was lightened alot and crack.
Craig might know of some billet cranks for one of those things, but you're not going to be getting any more than a 3.75"-3.8" stroke crank into it, the deck height will be too short.
Let me know if you need anything, I have a couple of odds and sods left over from the W8 engine I was building before I decided to go with a P7 deal.
