What do you guys think about going with the same specs as the TSP 231/237 cam but in a 115LSA?? I am currently building a 8.5:1 383 for my ATI D1-SC and i was wonder would it work with a higher LSA so not to bleed of so much boost. I really dont want to spin over 6500 RPM so thats why i am thinking about a cam thats not as HUGE as most do with a 383. Thanks

Seems like it would be the perfect plan. You want a cam with a higher LSA for the same reason as the low-compression. I have a feeling it would work out great with the boost.

Prob shifting the RPM too far up with that size cam and the 115ls.

Terry,
U think that it is to hi to shift at for a cam that big?? I have a 212/218 in there right now and it made power to 5800 and Jason at MTI put my shift point at 6100 rpm. I was told it is always better to go a couple hundred RPM's beyond a cams peak HP. Thanks

Grind some advance in and it will probably work. The bigger cubes should eat up some of the extra duration.

Ragtop 99, What do you mean probably work??? Originally i was going to go with a 224/230 .585/.595 on a 115LSA. Wich will work best with my new setup or should i go with a bigger cam??
Thanks, Kyle

Bring your ICL down, to 112 maybe?
Could you advance it 5 to bring it to a 110? or would that defeate the purpose?

I want to build cylinder pressure and not blead off as much boost as i would on a 112 or a 114. Thats why i am thinking about going with it on a 115. Anyone else have any input??
Thanks

kyle, z-rated is talking about intake center line not lobe center line. what he is saing is that go with the 115 LCA but install it at a 112 ICL which might work. the only way to know for sure if to change the ICL and dyno it every time until you get the best results. to get a good idea, as to were to start, i would call the comp cam help line and ask them what usually works for motors at those specs.
