hi guys. well first off i have 84 high sierra 2wd. Just put a 350 into it this past feb as it had a tired old 305. i got the motor from an 89 gmc. was my boss's old work truck and crate motor only had 50 000 miles. he said it was a target master. so i replaced all the gaskets and seals, re-manned the heads,mild polish,shave the deck .005, eddie performer intake, msd dizzy w/adj vac. advance, new quadrajet, converted serpentine back to my v-belts, and had to switch over to holley elec. fuel.
anyways, i installed a moroso advance kit, left my msd centrifugal weights which are 20degree, and tried a couple diff spring combos. righth now i think i have 1 light and 1medium spring. throttle response and low end torque is awesome compared to stock heavy springs. my question is there anything i should be wary of with having my timing come "all in" so soon compared to stock. i just dont want to be hurting anything when just cruising cause thats when i get the most timing because of the advance kit and vac advance working together. it doesnt ping or nothing and seems to run pretty good. i have it runnin a little bit on the rich side just cause id rather be rich than lean and until i find a "good shop" to get my carb set properly as with the timing curve, this is where im at. Im a perfectionist, to some extent at least, so i just want it to be the best that it can be. any thoughts will be appreciated!!! Lovin the site as well, i was at gmtrucks.com for a long time until i found this site and for me this is far superior-kudos to all
