Thread: need help not making no power

Tweet

i have 350 bored 60 over 4 bolt main set of speed-pro hypereutectic pistons with the floating rods and lunati cam .517/.543 lift cam mechanical lift with a set of double humps head 2.02/1.60 valves i have a holley street dominater single plane intake ihave it an a pontiac grandprix 1986 it came with a v6 but i haven`t change the rear end it because i feel like it should burn that one tire off of the car and i have a 2800 stall what do u all think is the problem and i have not put no headers on it i still have the chevy stock manifolds on it. could u all help or give me some pointers and i have 1.5 roller rockers

What gear ratio does the car have??? What carb??? What do you have the timing set at????

Trans slipping.....


Just roughly looking, that engine should be making power. What is the cam at .050, the compression ratio, carb size, and timing setting?

v6 back end or what ever comes in them 600cfm not a double pumper and the timing im not sure

11.1comp

The single plane could be killing all your bottom end. Does it pull on the top?

You're running solid lifters, what did you set the valves at???? What are you running for ignition???

I think some of the V-6 cars had 3.00 and worse gears......

not really it feel much better on the top in it seem like it take to long to get the rpm up

Most likely, between the cam and intake, you don't have enough torque/hp to get the car moving with the high gears. Need to check the timing. Start at about 34 total advance and work it up from there till it runs it's best. If your not running race gas mix, be careful of detonation with that high CR

Dave Severson has asked the key question....where are the valves set?????????????????

do u think the torque converter could be bad

convertor, maybe but not likely. What setting did you put valves at?

intake 18 ex 28

Why are you thinking convertor? Can you foot brake it? What RPM?

Thats a big spread. Is that the recommendation?
