Ford vs Chevy Build-up

Rory McNeil · 03-22-2015, 12:33 AM

Maybe I missed it, but what brand and primary diameter are those headers? I have FlowTechs on my 85 Mustang, but yours seem to fit tighter to the engine than mine.

Rory - Those are 1-5/8" Mac headers I bought used.

I hope you have more elbow room under the hood than my '68. The fit on my Hooker Super Comp headers leaves little room for error and can't be on the engine during install.

Everything looks great.

With zero experience on this car Dale I'm guessing I will need to lower the engine into the bay and fasten the headers just before setting it on the mounts.

I will admit to a rookie mistake. Went to drop the distributor in last night and found one must install the oil pump drive shaft when the pump is bolted to the block lol. Yes, I had to pull the pan to do it over.

I will need to be spot on with timing initially. Driver's side fuel rail is all in the way of the distributor body and precludes much rotation. Any more issues with these things and I will consider going back to the factory rails.

Actually, at this hp level, factory rails are more than adequate, just not as pretty, lol. For aftermarket rails, Behind Bars Racecars makes the best I've seen for clearing the factory distributor. Doesn't help you now, just mentioning in case someone else is reading this.

Yeah, I knew this going in but got a deal on those rails...not such a great deal so far haha. Not sure if a MSD is of a smaller diameter body or not.

Btw. I did not mention it earlier, but I tapped the intake for a 1/4" pipe plug behind that port in the thermostat housing (for a heater hose connection?). Figured that was better than messing with a cap of sorts.

Firing order 1-3-7-2-6-5-4-8, correct?

Plug is fine, and yes on the firing order. Stay with the factory distributor. More reliable than the MSD.
