As for numbers, my torque numbers seem slightly higher than the typical GT40 set-up
no, they dont..your bumpy tq curve poked above 300 for one quick instant..thats where your "slightly higher" peak # comes from
take a look http://www.allfordmustangs.com/forum...e264-gt40x.jpg
the rest of your tq curve avg is below 300 thru 99% of the pull
heres my old gt40p/Bcam,exploder intake dyno chart for "comparison"... http://i335.photobucket.com/albums/m...illmanTune.jpg
and heres a comparison between 2 gt40p/gt40 intake cars, mine with the Bcam, and the other with a TFS stg1cam..all the same "usual mods"..(the Bcam made more TQ and HP in the lower rpm range http://i335.photobucket.com/albums/m..._2278443_n.jpg
on off the shelf GT40 heads I think the XE270 is not a good choice.
what? the duration on the XE270HR is actually LESS than a TFS stg 1 cam
xe270hr= 218/224 @ .050"
TFS stg1= 221/225 @ .050"
the XE has more agressive lobe design, faster ramps, etc..it also has a wider 114* LSA vs the 112 LSA of the TFS1..if anything, the XE270HR should
be more drivable than the TFS1 without sacrificing any power
so i nguess in your line of thinking, the TFS STG1, thats been usedwith GT40's in successful combos thousands of times, id "not a good choice" then??
