Purists have said that about the V8 conversion.....mind what you say about 'sacrilege' on this site......

Check the basics: Plug wires routed correctly and not arcing or in bad condition (LT1s are very sensitive to spark breakdown) Make sure you have fuel pressure (invest in a pressure gauge that screws into the shraeder valve on the rail) If the opti is going out, you will usually have a slight miss at idle and a hesitation under load...it should at least fire unless its completely bad) Check for vacuum leaks. Make sure that all unused ports are plugged, esp. at the throttle body. Try unplugging the MAF, and let the PCM default to speed density. That way if you do have a leak somewhere the PCM can account for the extra air. Tim

1" inch square likely won't give much extra stiffening. Most use 1" x 3" or 2" x 3" x .087" rectangular tubing.....

There is no crank sensor. Everything runs from a signal from the optispark distributor.

According to my local dealership tech., the engine to chassis grounds are very important. I even ran 2 extra ground wires from the intake (2 rear bolts) to the chassis. Try that......

Update on the story:

Very nice, John!! Congrats! Quite the step up from the old Datsun and F250! Beta Motorsports must be doing well!! 8) 8)

Drill out the spot welds and pull of the rails. Inspect and replace, or put in subframe connectors.....That rust in the pictures really doesn't look that bad at all.....

I wouldn't be surprised if they nickel and dime this down the line to get rid of the pre-76 exemption....

Correct. This bill just halts the rolling exemption as of April 1, 2005.

While I totally agree with the argument, and realistically this Bill is a good idea, and probably overdue, since I have a vested interest in keeping my 73 car(s) exempt, I am against it, as well as being against regulation in general.... Tim

Here is a summary of the Bill: It should not effect vehicles that are already exempted, but rather stop any more vehicle years from falling into the exemption. Full text: http://info.sen.ca.gov/pub/bill/asm/ab_2651-2700/ab_2683_cfa_20040524_183247_asm_floor.html

Well...even after some lobbying by Jay Leno, Arnold signed into law AB2683 to repeal the rolling smog exemption! Bad news for us!

From John's first link....interesting.......
