650 and 760 motor ?s

[terenceferguson]

k i have a 91 superjet 650, i just put in a 760 motor. everything went in good, there are just a few different things between to 2 motors.

The 650 head has 1 hose going into it and the 760 has two, how do i hook up the other side?

The 650 has like a sensor that goes in the top of the head and there is a bracket that holds it down, but the 760 has no holes to bolt it to the head.

The 650 motor had like a 1/4'' hose going from the exhaust to the head but the 760 has no where to hook it up at on the head?

It started right up and sounded normal. If any one knows what i should do with these couple things id really appreciate it. Thanks

1.depending on your pipe setup you can block off the front outlet to force all the water into the pipe or run it to the front pisser w/ a restrictor like i did so i can still see waterflow.

2.even a stock 760 head should have a mount for the overheat sensor im unsure why yours wouldnt

3.block off the 1/4 hose at the stock exhaust

i have pics of my engine in my blaster (same setup) here

also i really recc a pipe...i ran mine w/ a stock 701 exhaust and it was a giant turd...the pipe really woke it up..also A/m head to bump up compression really helps alot to.
the 760;s dont have the same hit on bottom as a 701 due to the exhaust ports but they have a ton of mid range...if i keep mine its getting major port work that seems to help out the low end alot.

have fun
