thanks Bernie, pretty much how modded mine 25yrs ago!!
BASIC GOOD engine knowledge, what American Hot Rodders have been doing for close to 100yrs!
and Allen Scott also said Torque is King especially on the street, stroke it as much as your pocket book will allow!
what a lot of guys dont know, is the Jaguar V12 was engineered for Smooth ,Quiet , driving , when engineering changed from the V12 4 cam Hemi design ,to 2 valve single cam , power was NOT considered important!
your papers are spot on tho!
stroke it and GEAR it!

“Wouldn’t a change to a 700R4 GM transmission provide the lower first gear with an overdrive top gear be a prudent improvement?”
Absolutely!! Imagine cruising at 2000RPM rather than 3000rpm!!!
I fitted a 4L60e (later version of 700R4) to my Jensen Interceptor (3.07 diff) and that car is a fantastic cruiser. Interesting though, on this car, I’ve programmed the transmission to pull away in 2nd. With that 440ci (7.2L) torque factory, 1st is excessive. I can not only access 1st manually via gear lever. Never do it though.
Fitted a 700R4 to my '70 Chev C10 truck with a 350 V8. Likewise, good pull-away, but delightful at cruising.
HI Jagwit, i had a Camaro with 467cu.in(7.6L) BBC , it to was almost usless in 1st, so reprogramed the trans for 2nd gear starts ,AT LIGHT THROTTLE< But when pushed past 3/4 throttle it kicked down into 1st, and car started sliding all over the street, and tire smoke everywhere.LOL!
actually would lose forward traction and become slower!
it became a different driving experience!
after that ,when building my V12 5.3L Jag , i found V12 does not have a lot of torque,as most people think they do, they have a long flat torque curve , the torque they do have lasts longer and more RPM!
BUT sometimes you have already lost the race to a V8 car, so give some thought when modifing !
