after this 302 engine build

[Bad A$$ Coupe]

After I finish this conv 87 for my buddy with the heads and cam i did, i am starting on a new sheet of paper, I have my 1968 mustang coupe orig v8 car, still have the orig motor that was rebuilt (never used), looking to get around 400-450 hp, but since this is a new project from scratch i dont know what to go with, a 347 the stock 289 or a ls6 motor, i want to maybe turbo it, the only reason i am thinking ls6 or ls anything is because i hear great things from it... anyways let me know what yall think.... my ears are open...

Hmmm... whats the budget look like? Fuel injected or carb? A 347 is only going to make 400-450 in higher then turbo friendly compresion form. Boost friendly would probably get you around 350-375 rwhp. Maybe a bit more. If you are looking for 400-450 n/a then make it a 351 with a set of afr or tfs heads, a good cam and intake. Or put an ls6 in it.

A windsor-based motor will slide right into the '68. It will have an 8" rearend unless it's an original big-block car. '69 and '70 model rearends from 351 and up cars will bolt right in, too.

I would go with a 351w build. You can stroke that to 408. You can use your 289 and make it a 347 as well. But remember... 289-302 blocks are only good to about 500-550 rwhp.

Thanks, i am now considering the 351w, i am picking up the car today, its been at my uncles for about 4 years now and needs a lot of work! will take pics and post them tonight...

Make a 393, 351w block, 3.98 stroke aftermarket crank, 302 pistons, 351w rods, .060 overbore makes a 406. Cheap power.

You can build a 400-450 flywheel hp 306 for around 2500
