A question about Poly 318s
A question about Poly 318s
I received an inquiry from a Plymouth Owners Club member, about an engine being offered for sale. It's got the scalloped valve covers that are the hallmark of Polys - here's the information he emailed:
BTW - Faulkner's 318, which I bought from eBay represented as a '58 block, is stamped with LP8 + a serial number.
I've read that the casting number was shared among a number of displacements with the same block - just, different strokes and bores. But I understand from here, that the stamp indicates a '58 318. Does anyone have a differing opinion, or additional information? And, were the Fury 318's, different than the standard 318's in 1958 - and if so, in what way?POC Member wrote:On block in front of and below left head FLP8-072978
Casting number in front of and below right head 1737929
The engine and intake are painted silver with black valve covers.

FLP is the prefix for the 1958 Fury A engine. Special Fury 318 engine included re-curved dual point distributor, mechanical camshaft and dual four-barrel WCFB carburetors.

Dan: for what it is worth my Fury has the original motor and I think the car was made in June 59. The left side stamp is MP8326478 the casting # on the other side reads 737929 with A #2 above the numbers. I did not see A #1 starting at the beginning. Mine is the 318 with 2 barrel. Mark
ONLY ORIGINAL ONCE!!!!!

Mother MoPar, in her inimitable fashion! I suspect a 2-737929 block is the same as a 1737929 block, just a year later Thanks for the info, Mark.Mark Merritt wrote:Dan: for what it is worth my Fury has the original motor and I think the car was made in June 59.

Thanks, Rick - and apparently also a higher compression - 9.25:1 (according to the POC member who contacted me, but also corroborated by Bernie Brouillet). The "F" in the "FLP" is the difference.RICKYMOPAR wrote: FLP is the prefix for the 1958 Fury A engine.

Yes 9.25 CR but .75 less than the optional 350CID B engine.

You know your numbers Rick! the GC 361... (*sigh*.) It would be nice.
