Ok I'll give it a shot. I picked out a cam from Comp Cams, but I know everyone will say its too small for a 351W. Its a 208/216 duration at .50 and has a 112 lobe sep with 108 centerline. Lift is .533 and .544. This is a roller cam to be used in a 1995 5.8L block. This engine is to go into a 1990-93 Mustang GT.
Anyway my main concern is to keep the engine streetable, with excellent emissions, excellent gas mileage, work with stock computer, street range power band (1200-5500 rpm), and build the motor more for low to midrange torque then trying to get top end power.
My engine combo is:
1995 roller block 351W bored to 357 cubic inches.
15.9 cc dished forged pistons giving 9.64 compression with the heads
AFR 185 heads with 2.02/ 1.6 valves and air injection
Pedestal mount roller rockers- stock 1.6 ratio
stock crank with Eagle I beam rods- stock stroke
TFS-R 351W EFI intake
75mm BBK throttle body with 76mm BBK mass air sensor
BBK long tube headers with 2.5" collector
2.5" exhaust running 40 series Flowmasters and BBK shortened H pipe with cat converters
MSD 351W EFI distributor and stock ignition running regular spark plugs
K&N air filter in stock box
The last 351W engine I did- I put a Crane hydraulic cam into with 216/228 duration and the best mileage I could get from it was 200KM on a tank of gas. With that cam- the engine was rarely operating in its intended power band. This is why I'd rather go mild on the cam as long as I maintain street power and economy. The car will be a T-5 tranny stock and use 3.08 gears in the rear.
So Ed or Jay- what camshaft profile do you recommend?
