I RECENTLY GOT A MSD STREET FIRE HEI PART NUMBER 8362, IT COMES WITH STOCK ADVANCE SPRINGS{HEAVY ONES} WHAT WOULD BE A GOOD STARTING POINT FOR SPRINGS, MOTOR IS A 327--9.1cR---COMP CAM XE274 [274-286] [230-236] [490-490] VORTEC CYLINDER HEADS, EDELBROCK VORTEC PERFORMER RPM, HOLLEY 650 DP, TURBO 350...

where can i get a 10 degree can, or does anybody know a part number?

i think 44 is kind of high to, might try a different vacuum canister.

motor is 327--9.1 CR, comp cam 274-286 230-236 487-490. vortec cylinder heads, edelbrock vortec performer rpm, pertronix flamethrower hei ignition, turbo 350 trans, 2800 stall, 4.10 gears in a 67 camaro

hello everybody, with my vacuum advance plugged, i have my initial timing at 18, then when i hook it back up it goes to 44, i run manifold vacuum for advance, does that seem to high, will that cause idle problems?

hello everybody, i have a demon 575 mech sec carb on my 327, front idle mixture screws have hardly any effect, idle speed screws are 1/2 turn in on primary and sec, car is very rich at idle, eye burning exhaust, any suggestions.
