Lets see cam only and tune cars can go 420-430RWHP, am I right?
Do the heads for maybe 20RWHP, am I right?
Stroker bottom end?
Max RPM's?
Fuel economy hit?
Can anyone fill me in. Some of the motor builders are a bit disconnected on this subtle stuff.

Thanks!

There are no cam ONLY LSx cars making anywhere near 370 RWHP, let alone 420 RWHP. There are alot of head/cam cars making that though.

Stroker bottom end? Do that and you'll go way over 420 RWHP with a small cam.

7300ish RPM for a built stroker.

Fuel economy: Alot of people with 427 strokers and my 436 stroker are getting in the upper 20's mpg on the highway. In the city I get about 230 miles per tank.

The GOOD builders will know all of this info. You may want to NOT use the shops that couldn't answer these EASY questions.

Are you sure, maybe i read it wrong but i dont think so.

My SS is cam only and it put down 390/370.

So you added a cam with no bolt-ons or anything else and made approximately 90 RWHP and 70 RWTQ over stock RWHP/RWTQ?

Damn, I stand corrected.

the LS7 which is an LSx motor makes well over 420whp stock.....

You guys are to picky. Cam only usaully means cam only with all the bolt ons. Not to many people just install a cam and nothing else. That's almost pointless. There are some cam only cars in the 420 range, but they are few and far between. I'd say the average is 400 rwhp, cam only. Heads, depending on which ones you get, can add over 50+ rwhp depending on how bad the car is choaking. Stroker bottom end depends on which size you get. 400+ ci cars are cracking 500 rwhp, no problem. Fuel economy depends on how efficent your car is, in most cases, you fuel econmy is still really good if you can keep your foot out of it.

He's talking 346, cam only.

The LS7 is a 427 stroker with amazing new heads. So its a pure, authentic, forged and built super-stroker.

I actually don't quite know exactly what he's asking

when I hear of a cam only LS1 I assume it has all the complimenting bolt ons.

There are a few 383's making 480-500 RWHP on here.

Cam only is vague, but in general it means
Stock block, stock heads With cam + valvetrain + bolt ons

I change head gaskets but they say I'm cheating, I say why?
You change springs and p-rods and t-chain because your cam requires it, my cam likes head gasket change
