hello everyone, i have been asking this question in almost every other forum that i have found. And, i have seen that in here there are a lot of people that know what they are talking about. Here goes my combo. I would like to know how many hp will my l05 be really putting at the crank, because desktop dyno says that I will put 330hp, 450flb/tq.

Engine combo:
350 4-bolt-main
l05 heads unported
comp cams magnum 270h camshaft
edelbrock aluminum performer rpm intake
holley street avenger 670 cfm carburetor
flat top pistons
80gph fuel pump

thank you all in advance for your help.

forgot to mention I have 1 5/8 headers with 3 inch collector and an open exhaust.

Is it a stock bore and pistoned engine?? If so I would think that number is a little on the high side for stock heads etc. Also a pretty high torgue number for that cam with those heads etc. I would think that you would be somewhere right around 300hp and probably more like 390 to 400ftlbs. Just my thoughts though.

it is cut 0.030 and pistons are flat top pistons...

Well if your lucky you might see 330hp up top, but the torgue figure just doesnt seem right?? Best of luck though it should sound pretty good once tuned!!
