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 spin 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
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 all of us in the domestic crowd.
BTW
What is the MAXIMUM flow anyone can get out of E7TE castings and can you post some flow charts.
