both motors are on the ford racing website
now other than putting dish top pistons in both (cause im running twin turbo hopefully) which should i go with? give all opinions bad or good....now i do realize putting one big turbo will prob be cheaper an just as fast but...2 smaller turbos will spool quicker an besides IT LOOKS AWESOME!!! ive done major work to the outside of my car (if u look my sig says 95 gt but the pic has a 03 front end) and im wanting to step up the game under the hood to match im selling my lifted truck to pay for this new motor and have my mustang back

im leaning towards the 351 because of the larger cubic inches and the boost will respond better with the larger motor but something about a nascar spec motor just makes me smile:rolleyes:

thanks in advance guys

Depending on how much the block is you could build a bad ass motor for that. I have a 351 that I'm paying 2700 to put in a forged rotating assembly and stroke it to a 408. I was looking at crate motors and long blocks but then I realized they can be built with a lot better parts for the same price.

BTW a sealed motor means, it meets all the specs on the Nascar or latemodel rules... Meaning if you are accused of "cheating" they can see that the engine is sealed... but as soon as you take a valve cover off, it is no longer sealed....
