A local (St. Louis) Pantera owner ran nitrous on his 351C for several years.
Engine was a stock stroke 351C with L2379F TRW forged flat top pistons, closed
chamber 4V heads, Holley Strip Dominator intake, Pantera GTS headers and an
Ultradyne solid flat tappet cam. Made around 490 HP without nitrous. This was
a pump gas street car but saw 175 MPH blasts on I-270 while running the super
When the engine was pulled for freshening, the skirts literally fell of the
pistons on 6 of 8 pistons. Here's a picture of one:
BTW, there are two different pistons that were sold under the L2379F part
number. The ones pictured above are the earlier ones. The ones currently
being sold under that part number are Speed Pro pistons with coated skirts.
If you turn the TRW pistons upside down, you can see they all cracked along
a sharp edged stress riser. I don't know if it will do any good but I'd
round those off before hitting them with nitrous. The funny thing about
that engine was it didn't make much noise. With all those cracked skirts,
you'd think it would make a racket but it didn't. The skirts cracked
in a manner such that the skirt was contained by the piston while it was
in the bore but fell off as soon as it was pulled out of the bore.
Jerry has sworn off the nitrous and switched to a stroker 408C with C302B high
port heads, Roush intake and a solid roller cam
