I put the groove on my truck first and only truck I have done I had a great time the one thing I recommend to anyone thinking about doing a car is replace all vac lines I spent 20$ on a role of the small hose lines every turned out great.
hp very apparent improved
gas mileage has gone from 18 to 28
im still tweaking with carb for better cAs mileage
if anyone on is working on this let me know if u have questions
