In the end, you can can make ggod budget power with used heads and cams from the mustang or go with aftermarket ones and ported heads for huge power.


This motor will be getting a 35-50 shot of nitros for off the line jumps. and after tunning it it will probably get the normal two stage 150 shot just for sfatey reasons and don''t want to blow it up.

the toatl HP will be 415 with the first stage off the lineand 565 with the nitors through a two stage system total

wow... just glad a 5.0 is a lil cheaper on the wallet for parts

it is, but they don''t get 250K-300K in reliabliilty. Sometimes it costs to dare to be different

if anyone wants a 5.0 L budget build sheet, dyno sheet for proof,let me know.
