ms3 ) 237/242 .603 .609 112lsa

Ported 243 castings are a really nice budget head to go with. The cars around here (where I live) are making pretty impressive numbers and are pretty quick to have a factory casting head. As for cams both are nice I have experience with both and both are make pretty nice number, TSP makes nice stuff. Just depends on your needs,wants, and budget as to which cam is best. I would say give TSP a call.

 

i honestly am not sure how much but i know you'll get a good difference switching from 853's to 243's . . . . especially with that cam!
