valvespring info needed

I recall that lift is one of the reasons many people strayed from running duals on LT1s in the past, but .650+ is impressive. must be a good product.

[Shaggy67RS]

This is what I have in mine. They're duals, but to be honest I really don't know more than that. They were already in the car when I bought it, so I don't know what brand, etc.

Can you believe I'm still trying to learn what's in my own engine.

I went to my local speed shop today, and picked up a set of LUNATI double springs for $60. THe guy at the shop recommended them for the LT4 hotcam.

seat press 108
open press 339
coil bind 1.060
.630" max lift
.462 rate.

Is that overkill for a hotcam?

Yep, if the guy never told you and you bought it like that... How would you know?

Unless of course you take your car apart for fun

The LT4 Hotcam could use better springs than the LT4 springs right off the bat. I have heard the LT4s tend to float in the upper RPMs, but havent been to the dyno yet to be able to confirm this and fix it.

The Hotcam lift numbers with 1.6 RRs is only .525/.525 so, a set of dual springs rated for .630 max may be a little overkill... When I mean better springs, I mean something not too far above the LT4s... The LT4s are "barely" good enough in a sense.

Yeah, that's probably the only way. I've been learning as much as I can, but a complete tear down is probably still way over my head.

It was bought from a classic car dealer, so I never got to talk to the previous owner.

Thats ok, you will get there. And of course have some fun along the way

Is this the 67 or the 94 LT1? (If it was the 67, it obviously has some sort of LT1 transplant?)

Definitely! Already having a lot of fun with it.

It's a 67 Camaro with a 94 LT1 engine in it.

[Fixxer99TA]

Ohhhhh, here I am thinking you had two seperate cars

Nice combo though, must be fun to drive!

[Shaggy67RS]

Probably could word the sig better. Yeah, it's a lot of fun to drive!
