ThanksHey John the back half is the same,the extra ponies are suppose to come from the 7 pedal reeds and the ecu..I think a 96,97, 98,200 efi blocks are very close to the same specs as a promax..

Thats what I was thinkin too.

don't think so. the part# for the 200 pro max block and the stock 200 efi blocks are the same. the 240 sport jet and the 225 pro max blocks are real close. later Larry D

Agree with Larry,
The intake side of the block is different as well as the quinch area at the chest.The quinch on the 225 Pro max is deeper and longer like a 280.I modified one of them last week, it WILL wake one up big time...

The exhaust exit at the base is the difference.
