and i agree on the cam and 1.6 deal, i would just go bigger on the cam and stick to 1.5's, when you go to 1.6's you start changing things.

plus you get no gain with 1.6's if you're already doing a cam swap, just get one that is spec'd like you want with 1.5's and be done with it.

Well does anyone have any experience with hotcam?

Would it work ok with my 383? The specs on it are on the original
post.

I assume you're referring to the LT4 Hotcam, which is the only hotcam I've ever heard of. I've never run it, however it is spec'd using 1.6 rockers since that is what the LT4's ran. if you take the advice of keeping the 1.5's which I'd suggest, then it would be a little bit smaller than the specs you'll read about. I think there are alot of better choices out there. if you're using the stock heads (i.e. no porting/polishing) then the exhaust flow is where it's lacking the most. I'd probably look for a cam that is a little exhaust biased to help compensate for that. Here are a couple that may be worth looking into, however I'm no 383 expert, so do some good research on whatever you get. you can also contact companies like Comp and they can make some good recomendations based on your specs.

alright i was planning on talking to comp cams about it before i went out and bought something.

i was told by the engine builder today i would need to do anything to my heads if i got the lt4 hotcam.
before you question him, he has 40-50 year of experience and use to drag race too.
he loves the chevy small block, he normally runs carbs though so he doesn't have to worry about knock sensors.
that is why i came to yal.

thank all of yal i will update if i find a cam i want to

any more info is appreciated though

what has already been done to the heads? what springs are retainers are you running? have the heads had work done to provide extra clearance or anything?

 

[low98]

the heads and block were decked, don't know if the were ported and polished but if they haven't it can happen.
spring retainers i don't know

i am planning on replacing springs and some other stuff.

i want to get as much horse power and torque i can out of it i can to be honest.

everything is just money which i gotta save up!
