Is anybody running AFR 220/227 on a 396/408 stroker?

I see you're running 227s on a 396. I am also going to venture a guess that you are spraying your set-up. My concern with the 227s is loss of low rpm intake velocity, and I don't think I have enough cam to drive them either, hence my musings on the 195/210s. Would you mind throwing me a part number for your intake manifold so I can at least investigate that route. I really didn't want to go with a carb, but won't rule it out yet. Anyway, thanks for looking!

thats a SBC block not an LT1 block

I heard that they were working on an LTx block that should've been out maybe a year or two back - I guess they abandoned that effort?

They left us high and dry.

Just material?

Ability to run a larger bore would have been the biggest benefit. We are typically limited to 4.060ish.

Understood.

I never knew what they would have changed.

I forget the exact specs but I'm pretty sure you could bore it out to 4.200". If you stuck a 4" crank in it you could have gotten 443 cubes. Plus it is a lot stronger.

SHP blocks can be ordered with a BBC cam tunnel for no extra cost IIRC. Not a huge benefit but definitely one for the high rpm N/A guys wanting an SB2.2 setup. Just wishes and dreams now!

You got that right.

After this years Bike Week my money will start going back into my Z so I can finally get the new motor in and start playing again. I'm tired of looking at it sitting around collecting dust.
