An upgraded and Pro version of the popular SH.28.
It has a stronger Conrod, lighter crank shaft, 6 port configuration and updated carby.
A very strong engine and excellent value.

This SH 28 Prospec motor rocks..I run it in my savage SS and I give the hopped up Revos a runI am totally impressed with this engine. They mean it when they say 3.5 Hp. I run it in an Ofna Ultra GTP converted to a Dirt Oval Late Model. Horsepower is a must in this class and with the SH Pro Spec .28 engine I have been winning more races than ever.This engine is awesome.
It's got a 6 port and can be converted to roto-start easily with the adapter plate thats sold with it.
Heaps more power than the stock SH.28
