I'd say about 350hp.
A different intake would allow it breath better.

i got ripped on this intake ($350CDN) and e-bay ones are going for $70 US so since i havn't used mine at all i think it would be a waste.

ok you said "stock rotating assembly" so what compression are you making? the roush 200s have 64 cc chambers and depending on which year assembly you have, you might end up with a poor comp ratio. those roush 200s are said to be a pretty good head flowing its max in the 230 cfm range. performer rpm intake is definately a better choice with them heads, that performer is gonna give up at 5500.

74 would have i believe the D0OE castings which were 60.5 cc. correct me if im wrong anyone. your cam will not affect your compression ratio but your compression will have an effect on your cam. has the short block (bottom end) been rebuilt? if so give us your part number and brand of the pistons used if you know them. what is your deck height. if you could give me these numbers i can give you a close estimate of what your compression will be.

if the stock heads were 60.5 cc then i'll have about 8:1 compression

however i was under the impression that the stock heads would either be 58.3cc (CR 9.4) or 72.9cc (CR 9.28) and i had been told that it was the latter of the two.

nothing has been touched on the engine yet, 62,000 miles all that has been done is minor tune ups since the purchase of the vehicle in 74

i have a parts room that is filling waiting for summer

Your '74 should have D0OE-C, D0OE-G, or D0OZ-C heads which all have 60.4 cc chambers.
