This is my first post in the Hotsaw forum. I've used the search function without success. I've ported several saws with good gains, but all have had closed transfer ports. The 351 on my bench has open transfers and I'm at a loss. What can be done to improve flow and in the cut power on this type of transfer?
Here's the port timing numbers without a base gasket. Squish is .021.
Intake 72* abdc
Exhaust 108* atdc
Transfers 121* atdc
Blowdown 13*
Here's a few pics of what I've done so far, I figure on getting flamed for my crappy looking work so don't be shy, I can handle it.
Stock.
After widening the ports and changing the intake timing to 78*.
It's the transfers that have me puzzled, what to you guys think?
