Well completed my Second v8 Ranger a while ago. The 302 feel down on power and I am sure the 4.0l OHC pulled stronger in fifth gear. When I push is to about
100mph in 4th gear selecting 5th it will start losing momentum till it reach about
85mph. It will maintain 85 at full throttle.
The engine specs are .
302 block bored .040 over.
AFR 165cc Renegade heads.
Efelbrock Performer RPM intake
600 Holley with vacuum secondaries.
PRW - Roller rockers.
Mallory HIE dissy.
Edelbrock 2122 flat tappet cam.
Diff ratio left standard as on the 4.0l sohc 4.1
Gearbox Borg Warner T5 0.85 OD.
First suspected the Holley thinking the secondaries not opening testing it with a paperclip I found it to function as it should.
At this stage suspecting the cam.
Want to try a COMP roller cam part no 35-320-8 grind XE264HR-12 . As I have to convert to roller it is quite an expensive exercise here in South Africa.
Is this the best cam choice or is my current cam up to it and something else wrong? Help would be appreciated.
