347stroker_carb

i have a 347 stroker motor and the MSD distributor i have is aperrently locked out. i never heard of this til last week but maybe someone can shine some light on how to UNDO this lock out. the kit to unlock it is 18-20 bucks...but idk where they go...the shop will do it for $125 but im on a budget...any help will be extremely helpful..thanks

which msd distributor?? is it the 8598?? if so the spring kit controls rate and there is a bushing underneath that is replaceable that controls total advance

ill have to check on the part number but it sounds like an easy fix.

or post a pic of it.

it is a 8582 model...i had the weld grinded off and installed the advance bushing kit and so far its working pretty good...might just end up replacing it with a ready to run model eventually...i hate the having soooo many wires from the summit ignition box.

are you running a flat tappet cam or roller cam??

347stroker_carb

its a roller cam with 1.6 rockers..anderson N51HR cam and reverse dome pistons.

You realize the 8582 is for a flat tappet cam as it has a cast iron gear and the 8598 is for a roller cam as it has a steel gear..........better replace the gear or expect premature failure of the dizzy gear

didnt know that...thnx for the info...just the gear or the whole dist.?

i just got some longtubes for the headers and a new victor jr. coming in next month.


maybe that will help the ponies breathe a bit better.

have shorty headers and weind intake on it now.

also having an issue with rear end hopping on take off and extreme acceleration...u think traction bars would help?

get some better upper and lower control arms and I'd get adjustables so as to set pinion angle....also just replace the gear...I think the distributors are the same except for the gear but I'd call msd to make sure
