So would higher shift points!

Gotta know where your starting from man! , So i wouldnt say your runs are terrible, but sounds like there is def. room for improvement that you can achieve pretty easy.

Good luck.

Thanks I'll try out a new stall and see what that does. I was hand shifting it gonna take it to my trans guy to get the shift points higher

Please list your setup/drivetrain/mods.

I dont like to manually shift an auto. It usually does better on its own if its setup right.

It's a 454 the cam is a 240/242 595 that's is questionable, lt headers. Turbo 400 trans with 2500 stall that flashes to 4k. 12 bolt posi rear end. I think the gears are 373. I'm shifting into 3rd at the 1/8 mark.

If I dont hand shift it it shifts to early. There mite be more done to the motor I just dont know. He did say it needs a better coil. Hope that helps out a little bit

Yea I would agree with higher shift point. But only if you aren't feeling the motor run out of its power. It's a fine line to hit but it just takes some practice. Definitely find out what gear you have in the rear. 3.73 is a decent gear. I had a set in my old truck I had in high school. Ran great but I definitely needed a higher stall. I ran the same as you with a stock bottom end 350 with a 510 lift 234 duration on a 115 lsa. Had a mini blower on top. It was fast but definitely needed a higher stall.

Sounds like a 3200 stall is gonna be ordered along with nitrous kit to help the top end haha. When I get off my rotation and get home I'll update y'all on if I find anything wrong that would choke the motor. I am gonna change the carb to manual secondary's and see if that doesn't help some.

Thanks everyone for the ideas

What size carve do you have?? Anything less than a 750 its choking out

I'm not sure right off hand. When I get back I can figure it out. I just got this truck not to long ago and I'm only home 3 days out of 6 so I havnt messed with it just a whole lot. But if it's smaller than a 750 mite explain why I can't get over 5 k down the track

Yea possibly. Me n my dad built his mud truck motor which is a 454 all stock with a 555 lift on a 230 duration. Has a high rise single plane intake and a 750 edelbrock carb on it. Truck has 42 inch tires and it will turn those big tires over like they aren't there.

Makes me wonder if that cam he said is what is really in it. Good tuning goes a long way too. At least I got a starting point and can improve from there. Did you see the pics of it in the show an shine? I think there is a motor pic.

What kinda mud truck was it?
