find another machine shop.. and no short stroke engines don't rev quicker and spin higher
lighter rotating assemblies spin quicker and rev's are based on components not stroke

Lol I was looking at a 408 for next winter when I was thinking of going with a pair of 60s or 70s. Or maybe just 1 big turbo. Not sure at this point. Sounds like they want to charge a good lot of money for assembly. How hard is it to build a motor?

I think a 408 would be fine you just need to match it with a correct turbo. I see in your sig you a 70mm which would just choke a 408, you should probably look into a 88mm or maybe even a 91. For strictly race use a 408 could probably use a 106.

Whoever told you that is probably an old school guy that thinks a 1.300 tall piston is short.He doesn't realize that with todays thinner rings you can run a much shorter piston and still keep a thick top ring land.The 408 is a very good engine for boost if built properly.We have done several of them over 1000rwhp with no issues.Guys seem to thing you need to run short stroke on fi stuff-i'll take a long stroke any day.

Damn, I knew that my 408 wasn't worth a crap. Only made 1k+ rwhp with little baby 67's. I knew those 8 second runs didn't really happen. It isn't only the size of the block, but everything that goes on top and in the engine. Than you have to have a tuner that knows what the hell he's doing.
If you don't have confidence in the builder, DON'T DO IT. Why **** away your money (just pass it on to me - I can always use a couple more goodies).
