RB 413 IS IT WORTH TO BUILD
I like the idea of a 413 build. It is nice because they can use the bigger valves that even a stock head offers over the small block. And Lord knows small block guys can use all the port and valve they can get on there 4.00 (and bigger) arm strokers! Truly more the merry for those engines.
The newer intakes available are just great as well. Trick flow top end and a roller cam equal high rpm screamer ... if so desired.....
