I know the cam in the L98 is .410 but I can't remember what those springs are rated too. If you are going with a cam, you need to put the springs on those heads that the camshaft company recommends.

With your TBI engine, I would recommend a 212/218.

 

Anyone know what the actual compression ratio is on a 1995 CK1500, LO5, 5.7 TBI Vin Code K motor? If Its 9.3:1 now and I drop on 58cc heads man that would really spike the compression unless I stacked the head gaskets.

 

Its 8.3:1 on a light duty engine....on a heavy duty engine its 9.3:1. Your swirl port cyl. heads are 76cc stock is what most people have gotten...I have a set...just never cc'ed them. And your pistons are a dish piston with 4 valve reliefs. I can take pics of those if you want some. So, you should have a light duty engine can then with those 58cc, it should put you about 10:1.

 

If it wouldn't be any trouble, I'd kinda like to see some pics. I've never had a TBI motor apart before.

I think 10:1 would be pretty good with the right cam and intake.

Thanks again.

 

Its the same as any other 350 apart but I'll get you some. PM me your email address and I'll send you some tonight.

 

I found some on the net, thanks anyway..
