Cam thoughts? November 21, 2007, 01:48:33 PM Perusing the internet I came across this particular grind camshaft listed as a blower cam. http://store.summitracing.com/partdetail.asp?part=CCA%2D35%2D306%2D8&view=1&N=700+QuoteCam Style: Hydraulic roller tappet Basic Operating RPM Range: 2,000-6,000 Intake Duration at 050 inch Lift: 224 Exhaust Duration at 050 inch Lift: 230 Duration at 050 inch Lift: 224 int./230 exh. Advertised Intake Duration: 284 Advertised Exhaust Duration: 290 Advertised Duration: 284 int./290 exh. Intake Valve Lift with Factory Rocker Arm Ratio: 0.533 in. Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.544 in. Valve Lift with Factory Rocker Arm Ratio: 0.533 int./0.544 exh. lift Lobe Separation (degrees): 114 Intake Valve Lash: 0.000 in. Exhaust Valve Lash: 0.000 in. Computer Controlled Compatible: No Grind Number: FW 284H-R14 As far as the computer controlled compatibility I'll call BS right off the bat. My questions come about from looking at some other parameters of the specs......The High lift and Long duration would indicate an operating range a bit higher than the listed 2000-6000 RPM's. The wide LSA would counter this some and bring it down a little (less overlap = better idle, more vacuum, lower operating range, broader torque curve with less peak torque but wider range).Anyway, here's the questions: Seems this would be a decent N/A cam as well as a blower cam for aftermarket heads that flow well. What do y'all think?Also, PTV clearance with TFS TW's and flat tops?I'm curious how this sucker stacks up against my TFS stage 1. Quote Selected

Reply #2 – November 21, 2007, 04:46:27 PM I Think this is your TF Stage 1 cam http://store.summitracing.com/partdetail.asp?part=TFS%2D51402000&autoview=skuCam Style: Hydraulic roller tappet Basic Operating RPM Range: 2,000-5,500 Intake Duration at 050 inch Lift: 221 Exhaust Duration at 050 inch Lift: 225 Duration at 050 inch Lift: 221 int./225 exh. Advertised Intake Duration: 275 Advertised Exhaust Duration: 279 Advertised Duration: 275 int./279 exh. Intake Valve Lift with Factory Rocker Arm Ratio: 0.499 in. Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.510 in. Valve Lift with Factory Rocker Arm Ratio: 0.499 int./0.510 exh. lift Lobe Separation (degrees): 112 Intake Valve Lash: 0.000 in. Exhaust Valve Lash: 0.000 in. Computer Controlled Compatible: No Grind Number: HR-224/339-2S-12 Quantity: Sold individually. Camshaft, Track Max, Hydraulic Roller Tappet, Advertised Duration 275/279,Lift .499/.510,Ford,Small Block,Each Looks like that cam has a bit more than the Stage 1. Should work ok with the MA computer. You'de need a 2,800 stall converter, but you have that already;) It has about the same lift as my cam, but abviously more durration. I know that my cam is really viscious when it hits about 3,000 rpms:evilgrin: Quote Selected
Cam thoughts? Reply #3 – November 21, 2007, 05:12:35 PM Seems like a pretty big cam for the street - the 114 LS will mitigate that somewhat though. It has essentially the same overlap as the cam you are running so I guess it won't be too much of a change there. I run the XE270HR-12 (218/224/112 0.544/0.544) and I think it's at the limit of streetability, but that's me. Quote Selected

The torque curve though....looks like it would be a bit broader, but would it be a sacrifice of peak torque? Quote Selected
