57 Chevy, Dude! build thread

No problems with the 950's ? Mine were pig rich on my blown 540, couldn't get them leaned out, drove me crazy until I put the 750's back on. Signed hate guys like you...ha ha

 

@swade41 - Perfect air/fuel ratio, throttle response is sharp!
It's an 8-71 on 490 cubes, Dart Pro 1 AL heads and solid roller.
Gary Dyers recommended them, I'm glad I listened.

 

Mine are the Holley boost referenced blower carbs just like the 750's. I changed jets, power valves, idle air bleeds and even put the 750 metering plates in them to reduce the IFR 30%, still rich. Mine is 12% over 6-71, hydraulic roller that made just shy of 800 with the 750's 8% over making 3 lbs boost. It should take the 950's no problem, I'm wondering if I got a set of screwy carbs.

 

Hey now hey now. Don’t go trying to give me a big head or something. It’s a 30 year old truck with damn near 400k... but hey she’d do the deal!

This one came with some kind of specially set up 750s for the blower... should liven up a small block alright.

Post some pics of this super case M22 this weekend! I need to re-case my M20... or upgrade to a 5 speed... haha

Fun watching your thread! Why didn't they use a 26 spline input shaft on the M22? Just curious

 

Nice trans Steve.

 

Thanks guys, I went with the coarse spline because I already invested in an expensive Centerforce 12 inch clutch, and all my other cars have the same input. Hope it wasn't a mistake, Autogear says I'm ok.

 

A plus, it's got the deeper 1st gear, 2.56 : 1.
Something GM never did in the original M22.

 

Make total sense. Thanks
