L83 Cam Swap

[Jon A]

That would only be for a very, very extreme cam. None of the cams discussed here would require that.

I'm sure most of you know but don't forget about having to replace springs at almost every oil change. That's the worst part about cam swaps imo.

That's a ridiculous statement. If your not over .600 lift no need for spring changes on a daily driver. The stock LT-1 corvette cam is right at .575+ lift I believe and the beehive springs that are used in these motors are pretty stout not to mention the light weight retainers that are used.

My truck has 64,000 miles on the Lingenfelter gt2-3 cam and ls6 springs.

Can specs are 207/220 duration @ .050 lift -.571/.578 lift with 1.7 rocker 118.5 CL. The lobes have a very gentle ramp which is why the springs live. Its not a radical can so it didn't generate a huge boost, but a nice gradual gain.

I've been reading about CAMS....I'm not familiar with the CANS either.

 

What where your gains with the gt3 truck454?

[thetruck454]

I knew you would ask that, I wanna say around 30-40 rwhp. Lemme see if I can find exact numbers.

LMAO... I couldn't stand it!

Chuck at HHP is really knowledgeable on this subject

I just ordered a Gen V LT1/L86 cam (same cam)... $100 + or - . Pretty mild stuff. I don't plan on a spring change.

Spurshot... when are you swapping cams? I have a takeout LT-1 cam also and I'm wondering what the outcome will be. Waiting on you MAN!! LOL

I'm waiting for it to show up. I have a couple more mods to do in conjunction. Need to gather all the parts.

Does anyone have specs for the stock cam?

What are the specs on the LT-1 cam?

Any update on this? We are all looking to you!

A cam in the new DI motor is expensive. You have to pull the pan.....no more gaskets....all sealant.....sucks.
