Re: Straight through mufflers

a smaller muffler after the standard muffler used to be called a resonator, well it still is by the ricers. My parents brand new charger has cats, at least 1 muffler and resonators. The resonators are BIG. The guy that makes Classic Chambered exhaust, does a combo of the chambered 'muffler' and a g...

Re: Painted Connecting Rods?

Back in the days before corn squeezins were added to gasoline; guys used to paint a lot of stuff with Glyptal here. New Process used it as a sealant of sorts for some of their castings, so there was a LOT of it in Syracuse between NPG and GE and a lot of guys that came through those places as machin...

Re: Straight through mufflers

I use Classic Chambered mufflers with a crossover pipe. Sounds great, very vintage burble, a little bit of popping on decell, and thats without tailpipes, just turnouts Very reminiscent of the Turbo Tube muffler (same developer) and the original chambered straight pipes of the late 60s. American ma...

Re: Straight through mufflers

Those GM factory chambered systems were ear-splitting; I don't know how they could have passed any sound standard! [But of course in that era there were also such systems as the GTO V.O.E. (Vacuum Operated Exhaust) that laid down all the baffles via what looked like a vacuum advance canister...] Mi...

The weird 400-only length rods are a pain in the butt to get good piston choices it seems.

Re: Probably too pedestrian 283 SBC top end

Steve! Yessir! I popped together an M20 with some polished gears, caged needle cluster, lightweight sliders and a genuine 1960s Hurst shifter (came from what is now Mikey V's 4spd's). With the short tires and a snappy 1st gear; it held its own for him. Im still nervous about using solid lifters with...

Re: 307 Chevy with Vortec Heads

305 VORTEC's with 58cc chambers will run circles around the antique HO heads. You can grab a set pretty cheap, and sell the 062s easily.
520 casting 305 vortecs will produce numbers similar to grandads fuelie heads...AND they're 58ccs.

Re: SBC alum heads

Pro-Filer heads will more than likely outperform the Iron Killer and SHP type heads; and stack up very well with traditional AFRs, along with being American made. Approx.1000 bux a pair bare and 1200 for a loaded set. Thats for 195cc 2.02/1.60s (loaded was with hyd roller springs). Castings looked e...

Re: Probably too pedestrian 283 SBC top end

8 years! Wow! The kid in question is now married, and has a kid in kindergarten. The 283 ended up with the 113 vette heads, a GM composite gasket for the 305 (.026"?) a Performer RPM and a Holley 650 vac sec. Distributor for awhile was a old fashioned dual point setup, later he fitted it with a Cran...

Re: can Oil be TOO slippery ?

I once knew a guy who put some magic oil additive (PTFE based?) in a Peugeot 504 manual gearbox and it was slippery enough that the synchros refused to work. Some GL5 gear oils can be too slippery and can cause synchro problems in some older gear boxes with bronze blocker rings. How slippery was Ca...

Re: Engine swap ideas for a 1979 Mercedes 240D

Theres a pinto wagon around these parts with a flathead ford V8, T5 trans. The owner swears it has more pep and gets better mileage than the original powertrain. I keep trying to get him to turbo it or put a vintage centrifugal supercharger on it..so far, no dice.

Re: 72 corvette heads, manifold, and camshaft questions

Aren't the house-brand heads by either Jegs or Summit produced by Profiler? They should have a 180 head if you were willing to go that small. Buy em bare and have em loaded up with parts from competition products if you like; or just take the complete heads to your favorite engine builder to check t...
