We have some clown on our local street racing forums making some pretty outlandish claims about his 83’ Cougar with a 302 and 351.
Basically he persistently insisted that his 302 would rev all the way to 8000 rpm (later it was confirmed that he wired his tach as a V6, though he does not admit to it
) despite the fact that he was running E7TE heads which flow 160/120 stock and even with a top dollar port job can’t flow enough to feed an 8000rpm 302.
When we finally started to call him on the BS, then 302 blew up. A few months later he came out with a 351. Now he is running the same heads with the additional porting and bigger valves (yeah like those heads flowed enough for the 8000rpm 302 before that!!!! ). He has cited that the heads now flow 194 int 155 ex which is pretty much the absolute maximum E7TE heads can flow with a PROFESSIONAL port job and the motor now revs to 7000 rpm.
On a 302:
1) What kind of head flow would be required for an 8000rpm motor and does that indeed exceed the capabilities of ported E7TE heads?
2) Can the stock rotating assembly support 8000rpm, if not, what do you need?
3) What kind of valve train is required for 8000rpm, light weight valves, titanium retainers, fully rollerized rockers etc?
On a 351
1) At what rpm will peak power occur on 194/155 flowing heads?
2) He is running a stock truck cast iron intake manifold, can a 7000rpm motor run with this?
3) Again can a stock truck 351 rotating assembly live at 7000rpm?
Please help us finally shut this guy up! His mouth runs faster than his car which has so far only been able to keep up with stock Honda Civic’s and he’s just an embarrassment to the whole domestic crowd.
BTW
What is the MAXIMUM flow anyone can get out of E7TE castings and can you post some flow charts.
