Im a big fan of 114 lsa still sounds good and widens out the power band so its alot more fun to drive slow (pulls better in the low rpms you wont have to turn 5k to feel it) as for valve train I vote pac beehives if youre under .625" lift, and the lobes aren't too aggressive. You could go with a double spring but unless youre gonna turn 6 -7 grand everyday on your way to work it'd be overkill, and then of course hardened pushrods don't hurt. me personally I run the comp 224/230 .581/.592 114lsa in my DD with no prob, and it kept up with my buddies dyno tuned 233/239 cam @403 hp. Both of those cars are cam only (stock 853 heads). 228r would probably run better in the lower rpm and be easier to drive, but if you want her to thump, make all your buddies drool and really like that throw your head against the headrest feel dont be afraid to go with that tsp 233/239 even. That buddy of mine DD's that. Gonna need prc.650 lift springs though![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)

That is incorrect sir...the higher your LSA the higher your peak HP is developed...ie. a 114 cam will have a higher peak power rpm than the same cam with a 112 LSA or 110 LSA ... a car with a lower LSA will develope HP at a lower rpm ... if you want more lope at idle all you have to do is lower your idle rpm a little bit.
