LSA engine camshaft

I'm thinking of a camshaft for an LSA engine. I want to do what I need to do before I put the engine in. First, the camshaft! What about Lingenfelter Performance L210195297? The horsepower I'm looking for is about 600hp. Do the lifters, valve springs, and pushrods also need to be changed?　　　Since it costs money to swap, I would like to do the work in order.

Are you saying 600hp to the flywheel? Pretty much any cam will bring you there. That lingenfelter one looks like a decent choice, not too aggressive.

You don't *need* to do lifters but if the engine has some mileage you may as well. You will want to measure for pushrod length but most of the time should be 7.400".
Springs definitely need to be changed, choose dual .660's with titanium retainers.

Then, don't forget gaskets. Cam retainer plate.. timing chain depending on mileage, timing chain "tensioner" (the black trapezoid style), too.

If you are looking for 600 whp on a cammed but otherwise completely stock LSA engine, you may not get there depending on your drivetrain losses. I will tell you that I made 633 whp with a stock L92 shortblock, stock LS3 heads, shorty 1 3/4" headers, Summit 8715 stage 1 cam, stock lower LSA pulley and 2.5 upper. That was through a TR6060 and 12 bolt. At WOT it was around 10-11 PSI, and I believe the stock LSA engine is around 7-8 psi.

My suggestion would be to do an upper pulley and the cam now. Then assess if your fueling is up to more modifications.

Summit racing has some proven cam options especially for the price, put a little money back towards the other items needed for the swap as Dale noted

Concur with others.

Lingenfelter cam looks good, but Summit's 8715R1 will perform the same for less cost. Either way, you'll want .660 lift springs and titanium retainers as mentioned. Unless they have over 150k miles, I'd leave the stock lifters. Pushrods, as mentioned you need to measure for proper length with the new camshaft, and get some hardened with thicker walls for stability.

The bigger cam will reduce the effective boost pressure, so the upper pulley change is a good idea to get it back closer to stock. Or change both to get a couple extra psi over stock.

The Sum-8715R1 is a solid option, so is the Cam Motion Stage 2 PDS cam

I would like to know which parts to choose for your LSA power-up.
