I am building a 331 with roughly 450 horse. This will be in a 2500 pound mustang. This will be a limited use street car. It will spend time at the strip. I don`t want to loose a lot of low end. I want a radical setup, but not too much that it will only be strip oriented. Any opinions ?
I am not really shooting for a specific # on horsepower. I have just been basing my estimate on common hydraulic roller setups. I like radical setups, thats the whole point of this project. Is 500 realistic on 10.25:1 , AFR205`s, [email protected] .050" solid roller, Victor JR. ? I guess I`ll up my expectations
You can have a radical setup no matter how many cubes you have can`t you ? This is my first stroker. I have been told 331`s FEEL more lively than 347`s. I like rpms, I think this is a good compromise between torque and rpms. Believe me I have been racking my brain between the 2, and in my opinion this should give me exactly what I want.
Yes I agree you can have a wild setup with any cube engine. Now which will make the most power will always be the larger engine if it is built properly. I believe that the "feel more lively" is bs and just some dude's warped opinion. Just go ask some of the guys that have 347s over on the Hardcore 5.0 board that have N/A 347's that run in the high 10's that are streetable if they aren't as lively as a smaller engine, I guess then if this is the case why would anybody build a 408? I am not going to get into the 331 vs 347 debate. I think that is as dumb as the TFS vs AFR thread that are beat to death on these forums. Both will make a great engine for you starting out. Good luck.
Yes, I agree you can always debate the crap out of anything. Power should be relatively the same except for about 20 lbs. of torque difference, from everyone I have talked to. Why are there so many 331 kits if 347s are the clear choice?
