My stock 350 decided it was done not even 1k after my HCI build...found a good built forged 355, JE forged pistons, bored .030 over, balanced and stock reconditioned crank that i like locally, will be picking it up most likely this week but had a question about the cam that was in it. It has a 235/243 .602/.608 LSA cam in it. I currently am running a 227/235 .565/.579 110 LSA cam. Both cams are from LE. I will have the same beehive springs, pushrods, 1.6 rr, lifters, and LE2 heads in it either way. Exact same setup, what power differences are there? what kind of drivability would i see with the 234/243 cam? how much worse fuel economy?

That can will make more power a little higher then your current one. If its an LE cam, call him and ask how it will do, he should be able to give you a better idea.

You should also make sure that your current valvesprings will handle it as well.

think i should just swap my old one in? seems like alot of guesswork and if I'm going to be doing this, only want to need to do it once. Lol.

Your car was tuned I'm assuming?

Yep, shelled out 450 for a dyno tune. well worth it, car drove about like what it did a few weeks before when it was stock. I wouldnt mind paying for another tune for this new cam, if you guys think the power gain and drivability would be worth it? mainly concerned on the power gain. also i may add, this if my first actual "build" had a buddy do the first top end build. I wasnt aware if sliding the cam in was a process or if it was a piece of cake. I'm decently well with a wrench, Today after school I basically tore everything down, and the car is pretty much ready for the overhaul here by the weekend, just gonna give it a quick run through tomorrow and unbolt the headers and I should be game for saturday.

Exactly. Find out what springs are recommended for that cam and either get current ones tested or get new ones.
