I was considering a Magna charger 122, but Sean suggested building a 402 screamer. I have been debating it ever since. I pretty much decided that upgrading to a z06 would be out of hte question. My car is almost paid off and I don't want to make payments for an extra year or two for a used Z06.

Pros and cons of each:

402
1) 402 from A&A goes for $4k comes with a New CAM and has forged internals. I can probably get this for $6K installed.
2) I have EPT 205 heads most cars with 402 run AFR 225 heads. I think my heads might limit the power up top.
3) My fast manifold already has nitrous bungs. Forged internals means I can spray a huge shot (200).
4) 480-490 rwhp max without spray.

Maggie
1) 122 Maggie $6K plus new hood $1.5K.
2) 550 rwhp on stock LS2s with exhaust only.
3) No nitrous bottle to refill.
4) How close am I to the LS2 limit

Are you still planning to run your car on road courses? If so, stay away from the blower. If not, the blower is a great choice. Besides, you can always upgrade the heads later.

I still think a good N/A build would be best for you. Clearly you're much more into road racing than drag racing and I think a built N/A motor is better for road racing

Cough, cough, I think it was my suggestion , but since Sean agrees, it must mean one of two things:

a) it's the greatest idea ever
b) the Universe may implode

What are the draw backs on blowing a road racing motor?

It is not looking to good for any of us.

Generally they're more sensitive to heatsoak and also add more weight to the front of the car. Also, power delivery from a N/A powerplant is usually more linear than from forced induction (which is why Gordon Murray demanded an N/A powerplant for the McLaren F1) which is better for road racing.

Plus real men don't need to force anything.

Oh, Carlos, just rememberd. The guy who built the H&C LS1 in my Vette, now has a forged 402 Twin Turbo in his C5. As I recall he went with a Scogg & Dickey (mmm, spelling) supplier out of TX . . I think. Apparently the same specs as the A&A, but a bit less. I'm going to see if I can get him to come out on our cruise, but the weekends are family time for him usually.
