Thinking about a cam

Well the opti decided to take a dive on me.
After talking to a pretty fast Supra buddy I was telling him how I am throwing in some long tubes to go with the nitrous and all that. He told me that since I will have the majority of the stuff off for a cam swap with the opti replacement that I should do a cam swap. What do you guys think of an LT4 Hot cam on stock springs and all? I don't want anything crazy because I want to build a motor down the road. Any sugestions or will I be stuck pulling the heads and throwing in new springs and all? Oh and stock heads and a 3.42 gear.

Re: Thinking about a cam

The stock springs are not adequate for the cam.

Re: Thinking about a cam

And you can install new spring with heads on. As for the hotcam, go for it.

Re: Thinking about a cam

Get a hotcam kit if you want the hotcam, you wont get all the cam without 1.6 RR's and springs to match. They can be had for a bit over $400.

I am still wondering why a Supra guy is telling you what to do with your car? Did he used to own a LT1?

Its not a bad idea though, cams are fun peices of metal.

Re: Thinking about a cam

The Supra guy has messed with domestics quiet a bit along with the LS1/LT1 stuff.

Do you just put the piston at TDC so the valve does not fall down into the cylinder?

Air compressor in the spark plug hole works.

Re: Thinking about a cam

Yeah I have heard of that way also.
I just talked to my buddy and he knows a guy that would hook me up on head porting so I think we will just pull the top end apart.

Looks like it will be a three man job, one on the cam, two on the top end and exhaust

Re: Thinking about a cam

If you're going to go with a cam kit... and if you're not on a budget. Go with an XE Grind. I love my cam. I replaced my entire valvetrain and paid like $880 in parts.

Re: Thinking about a cam

Here's what I did (finished last week)
XE 230/236 $260 (thunder racing)
Comp 612 Valve springs $110 (combination motorsports)
Hardened pushrods $25 (combination motorports)
Gaskets ~$50 (discount auto)
Timing chain $40 (GM dealership)
Tuning $65-75 by pcmforless or madz28 (or free for me since I tuned mine myself)
Pro Mag 1.6 rockers $160 (summit)

Here's my dyno graph with this cam from today: http://www.fuelslut.net/hosting/uploads/Dyno.jpg

Re: Thinking about a cam

Thats with headers?

is without only pulling to 5450 on a tune for a 112lsa cam running pretty damn lean. I'm hoping for numbers like hers. More actually since i'm going long tubes. But you get the idea

Re: Thinking about a cam

I am having a hard time finding this but how much hp does a hotcam add to a bolton lt1 on average?

I'm curious how you got pro mag 1.6rr from summit for $160? I see them listed for $324.95.. even their regular magnum line (not promag) was listed for around $250.......

Let me know, cause I'd love to save nearly $200 on them

How does that cam compare to the LT4 hot cam? I know its about the same power numbers but is the power curve and different??


I assume I will need a TB also since I plan to at least port match and will have LT's and all???
