Don't know if this applies, but my Road and Track from June 1968 has a test of "Two Shelby GT350's - Cool and Hot" The regular GT350 had the 4 barrel hydraulic lifter 302 at around 250 hp, but the other GT350 they focussed on and ran their data panels on (and compared to the new Z-28) had a hotter engine. Shelby had "persuaded Ford to offer a new high-performance package for the GT-350."
This package added $492 to the price and included...
"special cylinder heads with larger valves (intake 1.875 in, exhaust 1.6 vs. 1.773 and 1.442), higher compression ratio (11.0 vs. 10.5), an aluminum high-riser intake manifold with a 715 cfm Holley (vs an Autolite rated at about 650 cfm), a camshaft that still works with hydraulic lifters but gives greater duration (6º greater intake, 8º greater exhaust)" and other minor suspension mods.
The article went on to say that the "factory people estimated it as having 315 bhp @5000 RPM and 333 lb-ft torque at 3800.
Personally, I think the standard J code (and the 68 Shelby) 250 hp engine was the "302 High Performance" engine. There was no longer a solid lifter hi-po, so the 250 hp version would be the next highest engine. And Shelby would always have the engine labelled "High Performance"for his cars. The mods discussed above in the article I think were just an option with no distinguishing engine code.
The TP 302 - a real hot ticket but I've never even SEEN one... I don't think the TP is the engine labelled as "302 High Performance", as Ford didn't release them for the street, although I understand a few somehow leaked out. (My father had a friend who was a radio station manager in Niagara Falls area of Ontario back in '68 who had a Highland Green 68 FB with a real TP 302/4 speed in it. He went for a ride in it, he told me it got rubber in all 4 gears....)
Sorry for the ramble, but hope this helps a bit.
