I want to buy a 351 dart block instead of stroking a 302 to 347.. I know there is a lot of debate on weight and having to change the bell housing and accessories but i think this will be a better move for me.. But i have a couple questions.

I am going to buy a T56 6 speed to go into my 89 as soon as i get the cash which wont be for another 3 months and i am building up my rear end with a auburn pro diff, 3.55 ring and pinion, 31 spline axles and c clip eliminators.

If i stoke the 351 to a 408 how much will it cost for the parts to build the motor and have a Performance shop put it together?
Not to mention the cost of the block.

I know this was a bit wordy but i wanted to give you guys the rundown on how my setup is going to look.

I want this stang to hit 180-190MPH and i think i could do that with the displacment from a 408. I also i am going to set up the stang to handle as well. maximum motor sports control arms, torque arm and panhard bar.

Any input will be great.
Roger

all in all, the shortblock should run in the neighborhood of 4500-5000, thats assuming an iron block of course. If your after an aluminum block, tack on another 2k or so

A dart iron block adds $2k to a buildup. Dont know about the aluminum version. I agree the shortblock you want to build is going to be in the 4-5k range. Forged crank. rods, pistons. Ouch.

I think the aluminum blocks are around $3800. Add about $1800 for a good forged rotating assembly. Buy most of the ARP catalog and get a $$$ oil pan so it does not go dry in those corners and you probably have an $8-9k long block.

It adds up real fast and the machinist will add more.

Engine Might have to get a Dart block but don't want to and if I do, then 363 instead of 331. Thoughts on what I've already bought so far.......
