Aug 22, 2007 · The L34 has higher listed valve spring pressures, so although the heads are the "same", there's a slight difference. Carbs are the same, Q-Jet with 1.38 primary, 2.25 secondary. Fuel pump looks different; L35 lists pressure range as 5.5 to 7 psi, L34 listed as 7.25 to 8.5 psi.

Oct 14, 2014 · re: 69 SS396 X66 L34 The work has been stalled for a while because I moved from Mass to Mich. I've finally been getting back to sneaking away to the garage. My plans are basically stock with a very few day two items. I'll probably be …

Aug 20, 2007 · I have a complete running 396 big block I may be selling in the future to build another engine.

Apr 28, 2021 · The Sealed power CS1093M is a copy of the 396/350HP L34 camshaft. It's 214/218 duration @ .050",.461"/.480" lift, and 115 DEG LSA. There are certainly better cams available for a mild 396. I would look for a cam with around .500 lift and an LSA between 112 and 114. If your on a budget the Summit Racing SUM-1301 is a nice mild cam.

Jul 18, 2005 · Believe the 68 AIM even references the part number #7028217 for the RPO-L34/L35 'A-1' proceedure - but, I don't have a copy here to check... If someone has the 1968 Chassis Service Manual at their side - check the carb application chart and see if there still isn't a side note on carb. useage for the Camaro 396's?
