I am sitting here watching Horsepower TV and they just built a 347 with about a 500 lift cam and edelbrock heads. 1000cfm throttle body and put it on an engine dyno and only made 370ish HP. does that sound right... I thought a 347 would be more like 400+. Thats what im building so i was just curious what your experiences were.

this could have something to so with it

hillbilly pony

Yeah... Thought maybe they were building it for a torque motor or something

i was watching that this morning to , but missed the dyno part kids and breakfast, it only made 370? seems a little low though, people with 347 and trickflow stage 1 cams are making right around 400 what the hell there?

hillbilly pony

Yeah. They said like 370ish and i think 384 torque. Cant figure that one

Didn't they say something about it was going to be used over at Extreme 4x4 or something like that. I heard it when they pulled the first run and it was like 306hp, I allmost fell outta my chair at that point, then the second run came out with 372hp. Small cam, big heads and fuel injection. Carb all the way FTW!!!!!!!

i think they could a played with some and got over 400

hillbilly pony

Definitely needed a bigger cam

88 347 stroker

its possible they usedlow compression pistons insted of the flat top ones they showed. I kept mycompression at9 to 1 because i have plans to supercharge themotorin the near future. when i had my car dyno tuned it made about 380 hp at the fly wheel.

And then some

Try this 347 on for size http://www.popularhotrodding.com/eng...347/index.html
