Anyone have any review or experience with this engine.

Click me.

I know this is sometime since your post but thought I would write to you anyway. I have used an SH .21 7 port engine. This engine was very fast. I used it some years ago at the SW tour in Texas and had no problems down the staights with anyone. The low end was great and a bit flat in the middle. I now have one SH .21 and had it flow tested and modifed further. This engine now is wicked and spent far less than $500 that the other guys I pass spent!!!

I'm looking for a .15 big block. Where'd you buy your 7 port .21?

Hobby people (?) I think is the name of the distributor and retail outlet for SH Engines. You can find their website on the RC Yellow pages. Seen to have excellent prices.

I would say SH is a OK engine...good enough to move the car.
But for serious big race........still far behind the big boys.
