The duel snorkel started in '70 so wouldn't all '71s have it?

Yes that is a create Gen V motor in it right now with electric fuel pump, came to me that way. I plan on running that until I have a chance to rebuild the original engine. Doing the Body and chassis first. I plan to keep things close to original with a few reversible upgrades in the suspension etc. I appreciate all the beautiful original LS5s out there but I want to swap out a few things to give it a bit of my taste too. Nothing that can't be put back with a few bolts.

I looked on the C3 Registry and couldn't find a '70 454 with a duel snorkel air cleaner.

Thanks JR, I knew you would know. I started at the bottom of the C3 registry page (high#) for '70's with 454's and I only saw open breathers. Maybe some people changed them to open breathers.

Mines a July 20 build with the dual snorkel type. I just noticed my engine pic on the C3 Registry is terrible or some reason. Guess I should figure out how to replace it.

Going to check for sure if it was the 12000 vin range or 14000 vin that the change was made

The change was made in the 12000 vin range and some early ones still had the open element

The current judging manual as I recall says both ignition shielding and air cleaner are acceptable both ways. My 70 LS5 had the dual snorkel unit on it, VIN is 158xx, with full shielding. I put an open element on since I find it more attractive
, but the dual snorkel is on the shelf.

If you two still want the mag, drop me a PM with an address and I’ll send them.
The package has arrived! Thank you VB!

A very kind gesture, one I'd like to repay!
