GodStang,

The 351 Windsor block 1969 or 1970 has high nickle content to support the factory 325 hp cobra jet engine. I do not recommend the 351 Cleveland block to anyone.....No Nada End of Story!!!!

The SVO 351 block is good to 800 hp. I hear the Dart block is good past 1000.00 Kevin Price, What are you running? I know Eric4 Nitrous is getting less fond of the SVO block.

I do not mean to stomp on AFR, but you should see the hassles they give you when their parts are wrong. I will not deal with them anymore, I would rather stick needles in my eye.

The Trick Flow R head is totally awesome. In a street fighter 427 block my local motorsport shop dyno'd the heads at 641 HP on gasoline only. He got 800+ horsepower with NOS and had not touched the ports.

Trick Flow is awesome to work with. They make the best water jackets of any FORD head I have ever cut apart. Full water jackets around the spark plugs, with ample water around the cylinder.

I had one guy on a thread say that his racer buddy friend said he didn't like Trick Flow because the water jackets restricted his porting technique.

Well, if you are building the engine right, the concentration should be on the exhaust side, cause the intake is not this head's issue. Just clean it up of gubbers and work the exhaust.

Then run the meanest high lift, low duration cam you can fit in the block and you are ready to take home the trophies.

Doesn't get easier, or more fun than this.
