which one and why?

Heads/cam. I have owned both. A heads/cam car will probably be more reliable plus it would cost less.

I say it depends on what you are trying to do. If you don't want people to know your mods, then go with H/C. They'll know it has a cam, but they won't know specs. They'll never know you have headwork done.

And as far as a blower, it's not exactly invisible. I have a H/C car and it's a blast to come rolling up on a Mustang, and the cam lope just scares the hell out of them.

It's awesome to put out high HP numbers being naturally aspirated. Give TEA a call and speak with Brent. He'll hook you up.

That's a hard question to answer.

The vette blower kits (A&A) are making 500-560RWHP very reliably on stock bottom ends and cost about 4900 bucks.

With a forged bottom end they can support 600-650RWHP easily.

The f-body blower kits aren't as well designed and can suffer from belt slippage etc unless extra work is done.

Maybe if there was something other than a centrifugal blower on the market for f-bods I'd take one... but there isn't so I wouldn't. Go with the H/C... then later on if you still want a blower, add it.

Turbo. One big enough to where it wouldnt start to spool until about 3k rpm's.

Seems a little contradictory.


I would also vote for h/c. Why? Lope. But that is just personal taste.

I have no "real" lope, but I still scare the hell out of them.

yea a good paint job and open headders will scare most cars off belive me i have a hard time finding races and my car is not that fast probally 11.8-12.0 range (no new times since new mods)

DONAIMIAN

iTrader: (18)

Ha if I could acually get a time slip that has a low12/high 11 sec run id be happy, instead of the normal 119 trap speed.

low 12's is not hard it = nittos, and headders, mabye a tune

Jpr5690

to secure it add a stall i ran a consistant 12.1-12.2 range before the stall

What exactly are you referring to? I must be missing something....

A blower is more likely to pass emissions if that is a concern. Heads and cam is more reliable, and has less plumbing to get in the way under the hood with NASCAR like motor sound as a bonus. Twin turbos have the highest HP potenial. If you're ever going to do any land speed racing, it's better to stay naturally aspirated for much easier safety requirements. That means heads and cam are probably safer on the street as well. No mater which you do, be sure to add the supporting mods so it is done right.

I say Heads/Cam. Just a personal choice. More reliable and less that has to go in it. Heads/Cam with supporting mods and 425+rwhp easy. And trust me after I got mine tuned, it pulled like a raped ape and has yet to not put a smile on my face

Well there are distinctive appeals to doing one or the other, whatever you do don't make a fast decision. Your ultimate decision make take into account new characteristics such as emissions, target rwhp, and drivability goals. I don't think anyone will be all over you either way you decide, blower or h/c. Consider another perspective, do both at the same time with a matched setup. From a GM High Performance Oct oh three, they planned on listing a chart with a stock cam, off the shelf cam, and then did a custom cam designed to work with N02 (but still nice idle). The specc'd cam ended up making proportionally more hp and tq, yet at the same time a low rpm friendly curve and better idle, which is fine. If you can do one or the other, and there'll always be a reason not to, in fact, a conservative matched set would be a good move for future longevity. Wherever you may end up envision the starting build and the target build, and don't be afraid to run a custom combination.

blower. the car will get good mpg and drive like stock.
youll also make more power than h/c guys

You could always do heads and cam first with larger combustion chambers then add the blower. Blower first is nice, but when you want to do the heads you will have to take it all apart again. Like some have said, the blower will make more power initially than a h/c car, especially dropping your compression on the heads, but in the long run if a blower is going to be added anyway you would be better off.

blowers cost to damn much... H/C...

blowers are a little pricey, but that's where the big power is at. however you can still make more than enough power with h/c to spank most the cars on the street. plus the sound bonus of a h/c car. pesonaly i think a H/C car is meaner than a blower. however if Kenne Bell ever finishes their blower for LSx's, i might i have to change my mind ( i think prochargers are lacking in the torque department). you can't beat that twin screw wine.
