L6 Power - Which Intake? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My '69 GMC is a pretty low mileage truck (32000) and has the original L6 engine. I'm a bit nostalgic about the L6 - it was the engine on which I learned about fixing engines. I'd like to do a few "enhancements" to the engine and start with a bigger intake manifold and headers. So..what do you say - Clifford or Offenhauser?

i'd say the Offenhauser. it has smaller diameter runners, which will help in the low to mid range power, more street oriented, where as the clifford is more towards high end power and racing.

thats my take on it anyway, way to keep it inline!

Yeah, not a GM, but I love it. 1969 GMC 32,000 - fix, drive, relax, fix... 2019 BMW R1250 GSA - Yahoooooooo 1979 Honda GL 1000 - retro touring at its best. Past: '05 Sierra 4x4 - Had 270,000 KM and running well when it was written-off by a stop sign runner. '94 F-150 from the "F word" company. I'll admit it...good truck. Sold what was left of it for $800 to a guy who came to pick it up at 11:00 PM with cash in hand. Hmm. '79 Sierra Grande (Black) organ donor - perfect rebuildable 4-bolt 350 and a good TH350. '76 Sierra Grande (Orange) - hate isn't too strong a word. Kid who bought it turned it into a hot rod. '68 C-10 R.I.P. - Dad's old truck...too far gone to resurrect. '59 C-50 - with hoist. Truck is gone, wife isn't. Nuff said.
