Re: after 350 swap car wont run

let me know about the vacuum lines. make sure any unused ports are capped. i just finished a 406 sbc build and got pissed off when i could not get it to idle. found i forgot to reconnect the brake booster so the intake vacuum was unplugged. fixed that and it runs mint.

Re: after 350 swap car wont run

Sounds like your timing is off to me. Rotor on firewall, check. Did you mark rotor postion on the base of the dist also?

Re: after 350 swap car wont run

Update i got it running after i blocked the vaccum port on the bottom front of the carb, and turned my distributor a little bit. But now it wont idle. i think i just need to time it and adjust the carb
