454 upgrade
Just seems that those kinds of numbers @ .050" off the base circle, are not going to hold much cylinder pressure under 3000 RPMs, even on 112 lobe centers . But OK, I guess you are the expert here ...........- AzGeo

What I read about that motor showed a pretty big cam for a street rod . "Just throw it in" ........ Yeah .- AzGeo

454 upgrade
I'm still trying to understand what you are trying to do, and yes I may have gotten the "Thumper Cam" from another thread, but .....? Is this going to be an "off road/race" vehicle 90% and 10% serious race truck ? I don't see why you would STOP at just 11.0 to 1 with oval port heads, while...- AzGeo

454 upgrade
Do you know what happens when an open chamber BB runs with LATE SPARK TIMING ? Sure, you could run it lazy pig rich, but why ? That kind of late timing will burn the exhaust valves out of that normally aspirated motor quicker than you can shut it off . With all due respect , I don't know...- AzGeo

454 upgrade
IMO, it's how and where you make your peak power . Back when I was in the boat business, I worked long and hard to bring "large oval port, cast crank, 3/8" rod 454 motors" up to a "usable power level", and have them live . NONE of them had 11.0 to 1 compression, that's not pump gas friendly ...- AzGeo

454 upgrade
I've run a "two bolt motor" with 5 to 8 lbs thru a little Rajay for 500,000 miles, with no failures . I'm now going to "let it eat", with a GM EFI, intercooler, and this T-6 Garrett . I'm going to limit it to 5800 and 10 lbs, once the tune up is close there should be no problems . This blower...- AzGeo

454 upgrade
I'm trying to understand some of the components and specs being given on this build . 11.0 to 1 is high enough to require "special fuel", but not as high as that same fuel will accommodate (12.5 + to 1) . I would think that building a "street driven hot rod", you would either go "pump gas" or...- AzGeo

fitech install om 77 c10
I have not been around for a while, but I am back working on my 79' crew cab . Been running it with a 'draw thru carb turbo system', and doing some freshening and up grades . Thing has been parked for so long that I will be installing a set of rebuilt heads, CC'd chambers, clean up surfacing...- AzGeo

Oldsmobile Engine Conversion
I've done a number of "403 into olds diesel 1/2 tons", but they were easy because the 260/350/403 gas are the same width as the Olds diesels. I think the 425/455's are the wider version of the motor. The larger motor may require the mounts be modified. The 'switch pitch' is nice, especially when...- AzGeo

lets see some square bodies on some 20'' rims and up
Have you checked out OEWHEELSLLC.com ? IMHO they have nice sizes and nice prices. -
Cam install ??
Hi, I'm new here but not new to engines, racing, or GM products. IMHO if you have A/C, engine oil coolers or trans coolers, you will have a hard time doing a cam install in the frame. Everything in front of the water pump must come out except for the 'core support'. IMHO I always must 'degree in...- AzGeo
