Spun a cam bearing in my stock block and screwed up a lifter/cam and other things...planning on replacing it with a 408. A few questions with upgrading to bigger cubes.

How much benefit will I gain from selling my fast90/nw90 to upgrade it to a 92or 102?

Would it be better to port/polish my 243s or buy a set of AFRs, Trickflow, etc.

Sell my LT 1 3/4 for 1 7/8?

Any other little extras that should be upgraded? Not necessarilly on a budget but at the same time I'm not loaded. Would like what everyone wants, A solid set up for a fair price.

I plan on getting a custom cam. Do I need to upgrade my fuel system or can stock with 42lb injectors do it? that's what I'm running now.

What kind of power are some you 408 guys putting down?

thanks in advance and also, sponsors if any of y'all are running any specials. I am still looking for a 408 block .

I would run the 1 7/8 headers for sure, heads depends on your budget. you should be fine with the 42lb injectors if your going all motor.

Interestingly a set of GMPP ported 243's might work very well with the setup. You're going to be combusting a lot of air plus require a ton of flow and the 243's have the capacity to keep it up. Although, if you don't already have a block you might have to find a better combination of block and heads, especially if you're going to bore it more than stroke it.

Prolly going to need a 255 pump for fuel.

Go w 1 7/8 LT's and get your cam spec'd first, then ask around for a set of matching heads.
