Would 400 rwhp be a bad assumption for this combo.351w bored .030 over.Trickflow twisted wedge heads that have been milled down making the compression ratio about 10.9:1 with flat top aluminum pistons. Trickflow stage 2 cam. Professional Products EFI Typhoon intake with 75mm t/b. BBK longtube headers o/r h-pipe and dyno tune. If you guys have any suggestions, please feel free 2 comment

 

400RWHP, may be a little high for that combo. I would suggest a better flowing intake, like a tfs R, or edelbrock victor junior efi, 24lb to 32lb injectors, 77 to 80mm mass air meter, 1 3/4" headers, 3" exhaust with either an H-pipe or a mac prochamber, at least a 225lph fuel pump, & 3.73 or higher rear end gears.
hope this helps

 

If you've dyno tuned why are you asking?

 

may because the op said he wants to get a tune! Hes asking if he'll hit 400 so he doesnt have to pay for a tune if he doesnt need it

 

well that is my current set-up without the tune. i actually have 42 lb/hr injectors for nitrous. and mustangmike_50 i have everything on ur list except a few things. Im actually running a 4:10 gear and i do currenlty have a 255lph fuel pump. SO roughly wat would would you guys estimate?

 

I think it would be close to 400.

I would look at a larger cam and porting the heads for upgrades. Would gain with a Victor Jr intake with an elbow too.

 

thats what i figured. Thnx man. i had a feeling that i would need 2 go bigger on the intake.

 

you can do some things with a windsor. There is a fella running one around here with a solid flat tappet cam, dome hyper pitons and ported 69 windsor heads with a small shot running 6.10s in the 1/8th. That was unheard of with the stock irons I thought.
