slow01z06

Hey guys, so I'm currently in the middle of piecing together a h/c/I for my 01 z06. I have the cam and fast manifold, I'm just waiting for the heads to be finished and assembled. They're ported/polished 243's with oversized valves and dual springs. As of late I've been tossing around the idea of going the boosted route instead though. I hear great things about the a&a kit, and was wondering if anyone has any input on the kit. I'm torn between keeping my plans or going the a&a route. Anyone who has tried both setups or has any input to help make my decision would be much appreciated! Obviously I know it's ultimately my choice, but before I spend all this money I want to feel like I made the right choice. This is mostly a weekend cruiser and only sees a few thousand miles a year with the occasional track day

You come to the FI section and think we might advise against it? Supercharge it!

slow01z06

Haha not hoping youd advise against it! Just want to hear a few opinions before I make a decision

I've done both. I started with H/C/I....then added the S/C. If I could only do one.....I'd do the s/c with headers and meth.

slow01z06

Yeah I have headers on the way soon

Depends on your goal. I ran my C5R block 427 NA for two years making around 520 RWHP, which had started to feel lame around the time the LS7 engined C6 Zs hit the street. I upgraded to an F1C Procharged setup and picked up 200+ RWHP, which put the smile back on my face.

If around 450-500 seems like enough, stick with Plan A. My guess: it won't make you happy for long.

Only thing to do to the motor is new V/springs in the heads if you more than 40,k on them. Then pin the crank...

I wish I would have skipped the H/C/I and went right to blower...

Rob Petyo

I like my H/C/I ... there are only a SELECT FEW

and still have a power adder if needed

slow01z06

I'm looking for a 450-500 hp streetable car that still gets decent mileage and can be driven anywhere reliably

slow01z06

60k on mine

sfc rick

I'm at about 150,000 on mine know.

ajrothm

Stick with heads/cam... Especially for track days.. Not it mention more reliable... Put it together, tune it and forget it. Forced induction is not like that.

Do both.

I would consider one thing that no one has mentined yet...learning to drive your car. Since you have much invested into the H/C, why not finish the original plan, learn your car, ;earm thenew power, how to best drive it, and how to enjoy....then when the time comes and you want the next step, add a supercharger to what you have already done.

Just a thought.

Every build starts with cam selection in mind. Then comp ratio. He needs a direction now or go 2 steps forward and 1 back. That being said, although I have a vortech, my twin turbo setup on my last car was by far more impressive. Although he has a small HP goal, we all have been there. That does not last long.

Shane1974

My bad. I just realized he only wants bolt ons....
Sorry

Then stay as far away from FI as possible.

450-500 is easily doable via AFR 205 heads, long-tube headers, and a modest 224 cam.

Unless you're looking for 600+ I would stay far away from FI.

I have both a NA 427 combo for road racing and a twin turbo 346 for drag racing.

I would go with a supercharger over H/C/I package as you'll get more HP, better MPG, and much better drivability. We've sold and installed WAY more superchargers than HCI for the reasons above. PLUS a supercharger is easier to install yourself than a HCI. If your interested in a supercharger give me a call and I'll give you a smoking price... and we offer 1 year 0% financing.

I have this exact package. AFR 205 heads, headers, and a 224-228 cam. I have been extremely pleased with it. It is so reliable it's almost unbelievable. I've been running it for 10 years and have done nothing but change the oil and sparkplugs. I have made 100's of passes down the 1/4 mile typically running 123-124 mph.

I had a supercharged car in the past and there were a lot more maintenance/reliability issues to contend with. In my opinion at the 450-500 hp level H/C is the way to go.
