I tried setting my tune at 19lb but it wont start just pops out the exhaust like a bad fuel\air mix.

This right here makes me think it's a valve or ignition timing issue.


The stock HO injectors are #19's (yellow). I also think that some 302s had 16# (grey) injectors.

one other thing to check is if you just swapped the intake to do the injection swap is a vacum leak. i replaced cam in mine and it would not start after installing and sounds similar to your start up problem. when i bolted the intake down the gaskets settled and exposed the tops of the port holes in the intatake gasket, could not see it by eye, but backfired once while i was watching it and saw the flame between the intake and head.

The intake gasket can easily slide out of place when the lower intake is put in place. A low vacuum reading is the tip off - less that 12 in. of vacuum at idle , no idle is possible.


My favorite trick that saves time and effort is the stay in place gasket. Be sure that you scrape (don't use a wire brush) all the old gasket material off, then clean all the surfaces with acetone or MEK.

When the surfaces are clean, use weather strip adhesive on the head to manifold surface. Also use the weather strip adhesive on the side of the gasket that mates to the head. When you are done, the head surface and the gasket surface that mate together will have weather strip adhesive on them. Follow the instructions on the tube or can and when it gets tacky, press the gasket down on the head.

Clean the area where the rubber rails mount to the block in front and in the rear with more acetone or MEK and do the same trick with the weather strip adhesive that you did to the heads.

Coat the rubber seals and the gasket area around the water passages with lots of Blue Silicone gasket sealer and put it together. TADA! no leaks, and no gaskets that shifted out of place.
