Advice on crate long-block (Jasper, etc..)

I have commented and provided advise regarding Jasper many times and will not elaborate but from personal experience and not heresay, a Jasper motor will not take boost for very long beyond factory specs. Period. Check the archives.......I know its a sin.

Jasper is a production shop except for Chebby applications. They bore everything .04 over. They buy pistons by the thousands, one size WILL fit all, its called volume. The head gaskets are incorrect and so will be the crank.

If you don't plan on twisting the tail on your car, then the Jasper motor will be fine. Otherwise plan on some down time.

Good luck,
