It's always good to hear when a combo built right makes great numbers. Heck, you could probably break into the 11s with slicks. That's pretty good for a 3800lb car.

BTW, do you have any flow numbers for the heads? And is that cam a hydraulic, solid, roller, or what? The FRPP manual doesn't list it anymore, so I was hoping you could share some insight.

Does anyone else hear notice that even small strokers make big numbers?

Basket Case

Thanks for that yeah I'm pretty happy with it. Today I took the lash from 28" to 25" and it came up even better.

Don't have any flow numbers on the heads, but they have been rebuilt and ported now 3 times so they are pretty maxed out as far as 2V's go.

The cam is a solid grind and they are pretty hard to find these days, there is some info on the web though. I was lucky the local speed shop could supply me with one. A great cam for a stroker, but I reckon for a 351 maybe too big for regular street driving and you would need to run more compression.

Currently I think my convertor is slipping excessively so I'm getting a bit let down there, that's the next thing to chase up and get sorted.

Because I have to get my crank ground I was considering building a 377 budget stroker. Could I get some more details on the Chevy Rods & ACL Pistons you used? If you would be kind enough to give me the brand and part numbers of the parts you used to build your stroker I would appreciate it. I have a machine shop that can do the grinding and balancing. Do the ACL pistons come with the valves reliefs cut in or did you have to have them machine in?
Thanks,
Doug

I looked up my invoice from the Engine Shop, he hasn't given me part numbers. They were 5.7 inch Chevy rods, and by the price I assume were standard ones with ARP rod bolts.

The crank started out as a stock 4MA and ended up with a lot of weight removal and balancing to get it right. Crank prep and the resulting balancing cost me $1k.

The ACL pistons are sold off the shelf as Stroker pistons and I'm sure they are easily tracked down in a catalogue.

Thanks for the try anyway.
