Looking for big block advice.

I was told by Howell that the TBI with a custom chip could stand a fair amount of power. I'm running a medium sized cam and their tech line said it was no big deal for the TBI.

Your accessories (pwr steering pump, alt, etc) will work you'll just need to find a bracket set for it.

Update.
I have a set of 046 heads and a set of 360 heads

You might want to ck the head numbers again. The 360 heads are peanut ports. The others don't come up at all. Closes is an 045 head. If you get the entire casting number it would be easier to figure the correct casting number.
