N-51HR Camshaft 2600-6500 Range

N-51HR Camshaft works with stock OEM pistons with 1.6 roller rockers.  Piston-to-valve clearance must be checked.  RPM range 2600-6500. Hydraulic Roller. Steel Core. Use steel camshaft gear.

Wildest and Best performer for 302 cu.in. 1.6 R.R. & 6500 rpm and 9:7 comp. Great with TFS Twisted Wedge, Edelbrock w/1.9 intake valve and AFR 165 heads. Must use Anderson Hi-Rev valve springs or upgraded PAC Racing Valve springs with a minimum 180 seat pressure. Minimum 24lb injectors and 80mm mass air. Recommend 4.10 - 4.30 gears. Poor drivability under 2300 rpm, lumpy idle, rpm range 2600-6500, needs 2800-3400 converter. Must check piston to valve clearance. 94-95 Mustangs will require a custom tune.

For best results we recommend a 4" Power Pipe® along with a minimum 75mm throttle body or larger. A "free flowing" and high performance exhaust system is also highly recommended. Custom tuning also will result with higher hp numbers.

Fits the following cylinder heads with stock OEM pistons from 87-95 5.0L

AFR-1399 Air Flow Research Renegade 165cc with 1.9 valves

TFS-51410002-M61 TrickFlow 170cc Twisted Wedge with 2.02 valves

ED-60225 Edelbrock Performer RPM 170cc with 1.9 valves

*Due to varying tolerances you may have to retard the camshaft 2-4 degrees to gain additional intake valve clearance if using stock pistons.

Note* Will NOT fit stock pistons on a 1986 5.0L without valve reliefs in the pistons

We do not recommend using with stock E7 or stock GT40 iron heads.
