Guys,
I have a 466ci motor I’ve been running for a while now. I burnt a piston, I am pretty sure my fuel pump failed me during a pass at the drag strip.
Now it is time to build a new motor. I’ve got a good set of Kaase SCJ heads that a Victor 460 (4150) intake. I think I want to build a good bracket motor. I’m thinking about ordering a stroker kit right off the shelf. My only concern is my heads have been milled down.045, I’m not sure if this is enough to create a piston to valve issue.
What is your thoughts….
Thanks

It depends greatly upon the camshaft but, stroker pistons usually have deeper than necessary notches so they clear almost everything except all out race stuff.

I would like to run a nice size solid roller. Nothing crazy. I not looking at the biggest and best. I am leaning more to the simple and low maintenance side of the spectrum.

Solid roller valve train and LOW maintenance don't belong in the same sentence.

You were going to check piston to valve clearance weren't you ? As long as you check your piston to valve clearance your milled heads shouldn't be an issue . Someone will correct me if I am wrong but ..090-.100 is what you want to see .When I built my afr headed 466 After I had my pistons cut for valve reliefs I had .100 clearance.And for low maintenance you cant beat a solid flat tappet cam shaft .RM who responded to your posting could have a cam ground for you .He did one for me and I am happy with it .Doug

Yes. I will check and double check all clearness including valve to the piston. Better to be safe than sorry. I ran a solid flat tappet for the last few years. I had no issues with it.

Solid Roller Cam is going to need more spring pressure than a Solid Flat Tappet cam and I think that's what Randy was talking about!!! Smile
