gt-40 crate engine dyno wtf

cool thanks guys

on the first attempt the shop used stock size gasket , on the last two attempts they used the 1262-r because as you and frpp said the only fel pro one is the 1262-r and the ford one is 9439-A50...So im trying the ford 9439-A50 this time see if it helps any...thanks 2000xp8,was wondering if you could comment about the bowl blending and valve job,, is the bowl blending porting?? thanks again for all the help too...merry x-,mas everyone

well it seems to be the intake seal was the culprit for oil getting into the combustion chamber...The ford gaskets that i had the shop try failed too though...The shop got hold of some better gskets through their engine buillder and it seems like they got it this time..the idle improved and my hp and tq #s peaked at higher rpms (more where they should be).. My new numbers are 255.52rwhp@5200 rpm and 292.42tq@4400rpm..They also did a run with a conical air filter and hood open and got another 4hp and 6ft-lbs-Do you think I would see the same gain in hp and tq with a jlt performance rai kit in the real world as they did on the dyno with the conical or should i stick with the stock air box and k&n drop in? Also the shop didnt want to go beyond 14 degrees intial timing and others have told me that i need at least 16 or 18...what do you guys think about more timing, is that the problem not enough ? Im still dissapointed with my numbers although im glad to fix the oil and intake problems as well as getiing my peak numbers at a higher rpm..
