In no way. Good "pernt" Bill!How would this be better than just building a 427 Cleveland to start with?
Sorry Ray, no offense, but you are wrong. 427 is the displacement, therefore making it NOTHING other than a 427. Since it is using a 351w block...than it makes it a 427w. I am getting very sick of this arguement. NOT ALL 427's ARE FE's!Please sell the real Boss heads to someone that can properly use them and find a modern alternative that will provide you better performance.. Please also refer to you engine as a Stroked 351W. 427s are FE big block engines.
I wish I knew more about this conversion, but don't they call that a yates??no offense mercougar67, but its a 427 cubic inch displacing 351w stroker, so...... 427w. and i definetly know how to properly use them, ANY way i see fit, just asking for help. the boss heads came off an ex drag car (ported, polished, 2.25/2.19 valves, etc) so i cant really use them on my boss 302 or even a 347, they couldnt make use of the flow potential from these heads like a big ci windsor, NA at least. i dont need another 351c, ive already got a built boss 351/408 in my capri. another reason (odd as it is) i would like to use these heads is they where built the same day as the block, trans and my car, all march 25th 1969. i cant justify spending 8-900$ on a stock 4bbl boss 302 intake and another 200$ plus for spacers etc. i know B&A makes some intakes, as well as the edelbrock e boss 351, and chi but they are for clevors, i dont know if the water ports are going to work with the b302s. unless somebody wants to trade my b302s for a pair of 429cj d0oe-r's, then this would fix everybodys issues lol
You are square on Cougrrcj! However you actually would call a Dart block 427 a "Dart 427". I have heard many of people refer to them as such. I think the reason why is they are not a automotive manufacturer...they are a parts manufacturer, so to call them a Ford is not technically correct. Although...who really cares. However, you can call the Boss 351w block that is stroked to 427ci a "Boss 427" because that is what they are. In fact, they actually have a boss 427 serial#. After all, Ford themself is who branded the Boss, so the way I think of it is that they are the only ones who can really make it "real".What do you call a stroked 302? Most people I know call it a 331 or 347, NOT a stroked 302.
I also call my stroked 351W a "393W". Just calling it a 'stroked 351W' doesn't tell anyone squat. What is the displacement now - 383, 393, 408, 418, 427? I draw the line at calling it a Boss though. If you used an aftermarket Dart block with Dart heads, what would you call it then -- a 427Dart? Chebby also made a 427. Caddy made 429s before Ford did.
Those 'purist types' that insist that only an FE can be called a 427 are living in the past. Get over it.
