Well, I'm gonna run the hotcam and ported L98 iron heads. Probably gonna use 1:6's also.

Questions:

1) Can I use the LT4 springs from SDPC withOUT machining?
2) Will these heads handle all that lift withOUT machining? If not, what machining do I have to do?
3) Will piston/valve clearance be an issue with STOCK '88 pistons?
4) Anyone else running iron heads and hotcam?

*Thanks alot for ANY help... I can't seem to find help thru the searches. There's alot of hotcam discussion and help, but not what I'm looking for. THANKS

 

ok in order
1. I THINK the springs will fit, I'll double check later when I'm in the shop.
2. No, the heads will not handle that much lift stock. You'll have to machine down the valve guides, no big deal any half competent machine shop should be able to do it for you no problem.
3. Clearance should not be a problem.
4. I think a coupla people are running the hot cam with the stock heads, but I'm not sure.

I'd say the cam would work well with the ported heads, probably an excellent match.

 

Thanks sooooo much. When I take the heads to a machine shop, do I just tell them how lift the cam has or how will they know how much to machine down?? Let me know on the springs. Thanks alot

 

Looks like the springs will fit. Just tell them the lift of the cam and have them check the clearance, they should be able to handle the rest.

 

I think you should just give it to me. Picked up the motor today and can't wait to put it in.

 

Thanks man! That helps me alot. Guess I just have to head to the machine shop now.


Rick- What are you wanting??? The zz4 cam??

 

I'll take that lt4 cam The way things are shapping up it looks like your motor will kill mine.:hail:
