I just wonder if it is worth the $400 swap for my planned combo? I plan on a 351 with the 64cc Y303 heads and a KB. I dont plan to rev over 5400 rpm. It will be for a weekend cruiser. Let me know your thoughts.

Building a 351 using 302 parts (to me) is some what down grading a 351. But if money is not a issue than by all mean 351 it is. Y303 heads are better than stock on a 302 but on a 351 I would look into something better for hp purposes, again this is just my opinion take it for what it's worth to you.
No, I appreciate your opinion. I just found a great deal on a flat tappet longblock, and I thought "what the hell". I was just gonna throw it together with what I have currently, but if it isnt worth doing, then it isnt worth doing. I wont fault you for saving me money.lol I wonder it Thumper could work some majic on the new 351 heads it comes with, or are they just E7's also? The motor is an 84/85 truck 351.

I would find out what the stock heads of that 351 flow. Seeing as how they came from a truck they are not geared for hp. Now if you plan on working the 303's then it may be worth the $$ to do. See what thumper or tmoss can do for you as far as making the 303's flow. I was under the impressing you weren't going to modify the heads just slap them on.
