I'm thinkin' they originally were for Nascar, but were banned. Ford then fed 'em into their drag racing effort before the cammer came along. Ironic, the Cammer got the same treatment from Nascar and ended up in drag cars, too.
No, NASCAR did'nt ban the 427 TP, they did ban the SOHC, however. Ford teams used the 427 TP quite successfully in 67 and 68 against the MOPAR Hemi's, but it was getting harder for them to do, the Hemi's would run away from the 427 TP's with one carb on board, so NASCAR actually let the Ford teams have the option of using dual 4 barrel carbs (which some of them did), all the while, the MOPAR Hemi's were still using one carb.
It was Ford who pulled the 427 TP's from competition as soon as their racing version of the BOSS 429 was ready. The 427 was no longer competitive against the mighty Hemi, thus it would take a Hemi to beat a Hemi! The BOSS 429 is a Hemi in its valve placement and layout, and just like the MOPAR Hemi, it too can move larger quantities of air/fuel than an FE based wedge head. There were some lesser funded teams that still continued to use the 427 TP up into the 70's, but they just were'nt competitive enough to win anything big.
Combine the BOSS 429 with the sleek new body of the 68/69 Torino and Cyclone, and it was an instant winner....in fact, it was the most winning'est body style in the ratio of wins per season. NASCAR today is very boring, I cant sit and watch a whole race, but I'll watch like say the last 10 laps.
you are wrong because ford was the maker of the hemispherical head. but scrapt it because the tunnelport gained alot more horsepower. the 426 hemi never out performed the ford 427 tunnel port. unless it was a crappy driver. and yes the 427 tunnel port was banned from nascar and lemans. the 427 tunnelport you are thinking of that barely ever got beat. was not the true 427 ford tunnelport sideoiler. but was a 427 lowriser top oiler that ford agreed to to level the field. thanks for the b.s. but i am jim craigs son. i know better than this crap! and the boss 429 cannot compare with a jim craig built 427 sideoiler tunnelport. I CANT UNDERSTAND WHY YOU WOULD EVEN COMPARE A TRUE 427 TUNNELPORT TO A MOPAR HEMI OF ANY SORTS NO COMPARRISON FORD 427 TUNNELPORT HANDS DOWN.
My father had a sanger competition bottom 18 ft boat with a ford 427 tunnel port that was blown. using a don hampton blower and a lenco set up this boat ran 147 in a quarter mile in the 80 s. the engine ran off avgas and methanol. it produced over 1400 hp.
not jumpy. just seems sick i was 14 years old and under at the times i was introduced to the 427 and know more than these people. the kung-fu thing is hillarious. if you knew my father you would understand! be like water haha.
No need to shout Grasshopper. Peace is easy within these walls.
I have no clue about this 427 TR, but I'm sure that if you wait till tomorrow there will be several knowledgeable replies I am sure...
I can google them but I won't, you see I love me a 390 not the 427 or 428 or 332 or 360 or 352 or 361 or any other FE design, they're just not my cup of tea, even though they're basically the same engine....
Yes I said google them. I was raised painting cars and fishing and shooting my gun's. I now Restore cars, I don't even know of a car that came with a 427 Tunnel Port, and I don't Race, and I cant' stand Nascar, so why WOULD I know something about them?
