i just picked up a straight clean 90 notchback, problem being when you pay for 8cylinders and only get 7 that tends to be a problem. so i've decided to build a stroker only problem is which one to go with the 331 or 347? the car is gonna mostly be a daily driver weekend track machine so drivabilty and dependablity are a must. i got a set of stage2 ported trick flow twisted wedges that are gonna top but i need a good bottom end to go with it. so what are your guys recommendations? what works and what doesn't is basically what i need to know. thanks alot for any and all help

This topic has been debated a lot. Please do a search and lets not let this thread turn into a huge debate.

Ive got a 347 with about 1400 miles and it is running fine. I would say pick which ever number sounds good to you. I would recommend CHP for a good bottom end.

Flip a coin: heads - 347...tails - 331. I have read good things about this rick91gt, but if you plan on doing it yourself, I got this one http://www.coasthigh.com/Specials/Specials_current.htm

This is too much of an opinionated answer and along with it will never come the same answer. The only true answer to the best dependabilty/least complications is to go with a stock setup.

For me, i'de go with a 331 though (again, preference/opinion).

I prefer a 331 for a daily driver or blown combo.

This topic has been debated eleventy billion times. Search the forums and youd be surprised what you'd find.


BTW if anyone tells you that the agressive stroke on a 347 will ruin your engine in no time....

Companies like CHP have offeset wrist pins to circumvent this problem.

NA or N2O 347 with as much compression as you can, any type of boost I prefer a 331.

All motor = 347
Power adder = 331
