issue after instaling high cams...

[93na]

after changin my block, i install 300/288 cams for my ride... was using this setup last time with no issue. but today when i install my cams i have this problem... my timing goes fromm500 to 2500 rpm and when i shift gear the rpm takes awhile for it to drop!!!...

like when i shift fron 2nd to 3rd gear at 2500rpm when i clutch in the rpm stay at 2600! it does not drop!! anyway know y this happen....

your cam overlapping is very high hence caused engine rpm stable while engaging gear and drop after a while. This is normal for such cam profile. Fast car doesn't sip petrol, it drink ! Your current engine setup very good for drag racing

Check your cam setting and tuning....
