Newly Built 383 Stroker w/Quadrajet
ykf7b0:
A couple years ago I did a Vortec head swap on my 76 L-48 Corvette and rebuilt the 17056202 Quadrajet with parts recommended and supplied by Cliff. The kit included 77 jets and 44 primary metering rods. I have since built a 383 stroker engine (10.3 to 1) to go into the Corvette and I am needing idea's on upgrades to the Quadrajet to meet the increased demand for fuel.

........forgot to mention the installed DA secondary metering rods.
Cliff Ruggles:
What are the rest of the engine specs?
May not need much for tuning, at least for jets and metering rods. Depending on cam and compression ratio might need more idle fuel and bypass air.....Cliff
ykf7b0:
383 stroker engine is 10.3 to 1 cr, camshaft is hydraulic flat tappet 279/289 with 225 and 235 @.050 duration, lifts are .465 and .470, factory vortec heads, aluminum dual plane intake, hei ignition, Hooker ceramic coated headers with 1 5/8 primary tubes and 2.5 inch true dual exhaust with Magnaflow mufflers, th350 trans and 10 inch converter with flash stall of 3200 and with factory 3.08 rear gears. I am also using the factory style snorkel air cleaner assembly for fresh air intake.
Cliff Ruggles:
Who made the camshaft and what is the LSA?
That is a lot of converter for 3.08 gearing, hopefully it is a custom built piece with very efficient characteristics above and below the stall speed......Cliff
