349 CI on the cheap
I just sat here and read this thread from start to finish. I must say I can't see any reasonable logic in building this 349 inch motor. $4,400 isn't cheap for a de-bored 360 with stock heads. Some people have the right idea on motor combos. I'm not in any way trying to dowm anyone's idea but I think some people are greatly mistaking the power range of this combo. In the last twenty years I have built every thing from a 192" strait 6 to a 738" 5.000 bore space pro mod motors. I have built about 15 small block mopars of various sizes and parts combo's. One of the nicest ones I have seen was a .030 over 360, 10.3 to 1 edelbrock performer rpm heads, m1 intake and a comp hyd 305/525 cam. Motor pulled hard to 6500, would melt the tires as long as you wanted it to stepping on it from a dead stop. Runs fine on pump gas and sound totaly awesome. I think total price on the motor build was around $3100 with new heads, roller rockers, cam & lifters, forged pistons, used intake and all machine work.
Something I learned many years ago, stock mopar small block heads just aren't good for making much power, unless you have a set of w2's I would never use a pair of stock casting heads. Not even magnum heads. Heads are where you are going to make your power. the edelbrocks are really nice and make power for the money and use all stock valvetrain parts. If you want more power and have a little more money to spend Brodix makes a pair of bolt on heads that use all stock valvetrain parts that have damn good flow numbers and can get you over that 500hp and close to 600 in street trim.
Just some food for thought on a more logical and less expensive way to make good reliable power
