Gday guys, sorry for another run of the mill "cam selection" forum question but I would really appreciate some advice on this one.
I am just about to start putting together a 221 for my XM Falcon now that my aluminium head has arrived. It will have a 5 speed manual trans and will only be an occasional driver.
Of course driveability is a factor but to be honest I am really after a beastly sound from the old girl to turn heads and get the V8 crowd thinking... The Falcon's paint is "farm fresh" which I love, people spend big dollars trying to get the same ratty look so I want an exhaust note to match its attitude.
I was all set to run a 274, 228 @ .050", 110° LSA solid cam from Schneider but it arrived damaged and when I degreed it it has actually been ground on a 107° LSA.
I also have a Clay Smith 278, 230 @ .050" (measured), 108° LSA solid cam but its measured lift of .475" is lower than advertised (.505" with 1.65 rockers)
Basically I cant decide between the Clay Smith 278 that I have or perhaps ordering the Clay Smith 292, 240 @.050", 110° LSA from Mike?
Other specs are:
221 from an XT Falcon +.040"
Aluminium Classic Inlines head, dual springs
Flat top Hypatec pistons, zero deck
Yella Terra 1.65 roller rockers
DUI recurved by Bill Ambler
Compression to suit final cam choice (will be approx. 8.5:1 dynamic)
Classic Inlines 4 barrel manifold, Edelbrock 500cfm carb, 98 octane fuel
Headers with dual 2.25 exhaust
Celica 5 speed, 3.5:1 diff, 1200kg approx. vehicle weight
I can put up with it being a pig in traffic as most of my driving is on open coastal roads but I don't want it to be a total mess...
Any advice appreciated
