engine rebuild

Seriously though, dart 347 with an on3 kit will easily exceed 500hp. You could do it on a stock block but then we'll see a post that says my 347 is now a flower planter.
 
400-500hp is alot of power so i would look at supercharger kits or turbo. get good flowing heads and a cam that fits a boost motor. keep you CR down

?????????? seriously? I know a guy with an autox car who makes well over 400hp with an n/a 306.....:shrug: I allways thought turbos were for when you wanted to make 700+hp.
 
hmm. yeah, ok. I really quit trying for big horse power out of 302's about 20 years ago when I got my first 351w fox. (357) it made around 425 with no juice. Not saying 302's are bad!!! I just got into the displacement thing and thought, crap why waste time! Still scratch my head when someone is jazzed over a 400hp supercharged engine.:shrug:...no such thing as a 347 back then!.. or a 408:Dhehe!
 
450rwhp in a 2900lb with driver fox will scare you

I had a hundred shot, well a 300, but only gave it a hundred. A guy I kinda knew stopped at a red light next to me one day on his 750 katana. and I had my m&h racemaster slicks on that day. I sprayed it out of the hole. he about **** when I did a wheel stand and ran off and left him. That car ALWAYS tried to swap ends. it was like a never ending power slide. lots of fun. when we stopped at the next light he flipped his visor up and yelled "what the **** you got in that thing? LOL!!! When I put it up for sale his brother bought it!!!
