Well guys, I am starting to put the money aside for my motor build
I am doing a 383 build w/ LE-series heads, thinking the LE2 heads

My thing now is the camshaft. Are there any advantages/disadvantages of a solid roller vs. a hydraulic roller?

I am really looking at this camshaft but idk if it will be too big or what.

Its either that, or a custom grind

I am trying to get 450RWHP or more, and a friend told me that he believes a solid roller would give more power, and after seeing 526 SS's SR make those #'s, im a believer

 

SR cams can make more power because they have more agressive lobes. The ramp rats are much more agressive because the lifter can handle it. If you ran rapm rates like that with a hydraulic lifter you would trash the lifter in no time.

There are many advantages and disadvantages.

Some of the downs to them are valve trains. You need high dollar parts to handle them, Bigger valve springs, stronger rockers, better flowing heads, better intake, frequent valve adjustments, ect....

But on the plus side you can make more HP, more TQ, turn higher rpm's...

In the world of SR's that Lunati isnt a "huge" cam by any means. Its more of a mild SR especially in a 383. (my SR is 263/270 going in a 355) With a good set of heads/intake you could be close to your goal of 450. The better your supporting parts are the better your numbers will be. I can tell you right off the bat your not going to use a small spring like the behives on that cam. Your going to need something that has 200lbs+ on the seat.

Is this a street motor or a race motor?

 

it's a street motor. I PM'd bret about it and he has gave me some ideas, but not many.

 

its tough to build a reliable SR street motor. You have to spend alot of money on better parts to keep the valve train stable. I'm a big fan of just using HR on teh street and SR if its a race engine.

 

so should i just go w/ a LE3 and a big HR cam?

 

I would for a street motor. Less maintenence, more drive time. An LE3 with a good cam and you could still be up at your goal.
