More HP ... Blown 302/347 or Blown 351/408? Turbo 302/347 or turbo 351/408? etc., etc., etc. All those power adders reduce reliability where as a windsor upgrade is essentially as reliable as a 302. I'm assume(don't have the numbers!) a naturally aspirated 393 is an appreciably cheaper build then a turbo or supercharged 302. NO2 setup is cheap intially, but NO2 isn't free, and you still need a stout bottom end or you won't have fun for long, and you need to fill the bottle, and general only used for racing. Which is fine, I'm just point this factor out. So, I'll say YES I agree the all replace the horse power (and then some depending on the details) but still are not a complete replacement for cheap, reliable, gruntin', pullin', good old fashioned displacement
What was the original budget for this build??? Because I think I can see things starting to snowball, and the build taking much longer to complete!!!
I would put in the engine that fit (302-331-347) then if that's not enough apply a little boost later. Of course that depends on budget.
There are several that fit... Not just the 302. Some just fit tighter than others. If you want a bunch of room, put in a 200. If you want a bunch of power, put in a 408w or c.
Hey guys, Have your cake and eat it to. The Man-O-War 8.2 deck block can be stroked and bored past 400 ci.
I am assuming that he meant V8 since he didn't mention the sixes. I was referring to the fact that the 331- 347 is a direct, easy drop in with no shock tower/ header/ spark plug access issues. And should easily make all the power you need to run easy 12s or 11s with the right parts. That is a bunch of power. Not dissing the 351s. I have a Cleveland. They are great.
It was nothing personal. I was just stirring the pot, so to speak! I do that alot around here. Some folks 'get it', and some folks take me too seriously.
Oh yeah! I love those things. Wish I could afford one. 8.2" deck with Windsor pan rails so you don't have to worry about clearances. It has to use a 351w oil pan, distributor, and oil pump. Add the option of siamese bores and you can run 4.125"+ bore! However, I believe the 9.5" siamese block is not much more money! I mean if you have enough for the 8.2", then the 9.5" is only relative pennies more. Then you can get within spitting distance of 500 cubes, if you're brave.
A 351 will run better stock, and will run better in a milder configuration simply due to more cubes= more torque. All things equal, bigger motor wins. BUT-the 351 will need high $ headers to perform well. And 351 parts(intakes/rods/pistons)are a bit harder to find used than 302 stuff. The 351 is a tight fit though. You'll need a remote oil filter,or use a shorter one for a 318 Dodge. A well thought out 302 will run good, is easier to package and used parts are almost as common as 350 Chevy stuff. If you're on a dirtball budget, a good running, stock exhaust manifolded 351 is the best bang for the buck. It'll be a tire burner even with a 2 barrel. If you got cash to work with, I'd look for a roller cammed 302, sprinkle some speed parts at it(intake/4 barrel/headers,etc)and go from there. It'll be much easier to put in, work on, and is a bit lighter so you can at least outcorner a dump truck. Have fun.
Not enough choices in intakes IMO. Same with the 8.7"... If you want to run something other than a Victor, you're more or less skrewed.
