willys1 said:Not to change the subject(hey wait a minute,its my thread ) you hit the nail on the head about the hp rating on the afr 165's(41hp) what do you think canfields are?They make a set specifically for 5.0's.
If your gonna take it all way down to the heads its only about 1 hour more work to install a cam. You can do it with motor in the car. But if you decide to keep the stock cam. Go with a off road h pipe. Youll benifit from that.willys1 said:If I go with the thumpers,could I get rid of the tail pipes,or cats? Or am I gonna still need back pressure with the stock cam?
Thats why Im askin,,I have a BBK off rd h-pipe,but took it off because I lost alot of bottom end torque!!5.0Droptop said:If your gonna take it all way down to the heads its only about 1 hour more work to install a cam.

rsw007 said:the thumpers will flow more than the stock ported lower will flow so i suggest a better intake. the low end wont suffer much with your converter.
Looks like I just saved 500 beans on a new intake Hey Tom,could I now lose the cats or take my tail pipes off? or will I still need some back pressure for the low end?tmoss said:Actually, I can get the stock lower to flow more than 210+cfm, but it doesn't make sense to do that since the upper will limit total flow to the mid 190cfm range. My "standard" port work on a lower was flow tested at 195 cfm average.
5.0Droptop's SOTP was verified in 2 dynos of Rio5.0's Thumper headed Steeda #19 cammed car. He went from my ported lower and his massaged inlet (65mm) upper 95 intake to a Cobra intake. Average power over the 3,000-6,000 rpm band was virtually identical with the ported stocker making more power up to 4,200 rpm and the Cobra making more power to 6,000 rpm.

I love experiments with noisy (but nice noisy) exhaust systems!! Im getting a catted x-pipe from Bassani,,with the new all Metal cats It should flow alot more,Im getting sick of the h-pipe dronetmoss said:In most cases some level of backpressure produces best torque and power for a street combination. It would be hard for me to say if that was a good move or not. Different mufflers have varying amounts of pack pressure too. Most people have to experiment to find the right amount.
