Re: Time Out: 70 El Camino Side Project

Time for updates....

It seems there was more going on than just the generic Holleys issue. It was not just the carb. Turns out the el-cheapo notebook paper thin carb to intake gasket blew partially apart @ one point (most likely during one of it's backfires). It was actually split @ 3 different points.

Unfortunately, after swapping the Q-jet over, it still didn't seem to have the power I/we expected. It ran.... but not like a typical 350 should power wise (my 245k 6cyl/5spd 90swb had more acceleration get-up & go). After playing w/things we ran out of time so left it as is to think it through.

A buddy of mine suggested another pass through the ignition circuit. This was where we found the other items. It turns out we weren't getting any advance from the distributor. The vacuum advance canister was dead & we found the mechanical advance cams stuck. A new adjustable advance canister was swapped in place & I cleaned up the advance cams + added new springs.

What a difference. Now it pulls like a 350 should. It still needs other items addressed to be optimum but for a DD it's running the best it ever has. Future 'wants' are 3.42 or 3.55 gears, possible converter change, & an OD trans.

Last exterior item addressed was the bed area. It had a vinyl bed cover @ one point. But when the pass rear quarter was replaced, the snap bases were removed. The debate was clean up the drivers side & go w/a nice 'in-bed' solid frame cover or drill the new quarter for new snaps. This was a tough decision but ultimately the budget dictated another vinyl cover.

My buddy whipped it out over a weekend & right on time for Senior pictures.....

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
