get the block numbers from above the starter and ill check my book.
manifold bolts-
W= in a row
C= at a 45* angle but with same bell houseing as a 302/ 351w
M= at a 45* angle but with a bell that is the same as a 429/460
also look at the starter, if both bolts come from front its a small block, if one from front and one from back its a big block

ill check my books in the morning for the stock HP rateings. is it a 2 or 4 bbl carb and does it have 2 or 4bbl heads (look at the front corner of each head, you will see the number inbetween the intake and the valvecover on the head) sorry best i can explain that.

IF it's a '74 351, it can't be an M, might be a C and is probably a W.
As for HP/TQ, stock "net" HP from '74 W would have been 150-160 or so, compared to the pre '71 250hp for the 2bbl, 290 for 4bbl gross hp figures. Torque in high 200s, approx. Someone may have the exact numbers. Add your long tubes and subtract wear and tear. Who knows? If you fiddled with it to make it run good with the headers, say 200 net. No one will challenge that.
Figure out what it is though...that will be important.

Here you go
1-The D2AE is a 351c block.
2-351w intake WILL NOT work on this engine.
3-351c and 351w do have the same bellhousing bolt patterns.
4-351c IS NOT a "big block"
5-351c and 351m/400 use the same 2v heads
