I have a 434 cubic inch small block with 15 to one compression. I run a rons flying toilet where is the best place to run the timing? Ive had some people tell me to retard and others have said to advance so could some one set my straight on this.
thank you

32-34 Degrees

My 434 with toilet liked 32 but yours may not have to play with it a bit.

thank you for the reply also the engine is 800 hp I run 36 nozzles and usualy a 84 to a 90 pill been playing with timing about 32 degrees and my 66 nova at the end of the season on a cold track with worn slicks ran 9.04 car weighs 2640 with me in it and sixty foot about a 1.28 with 430 pro gears in the rear dana 60 and glide with a 180 straight cut gears does this sound about right? rear tires are 30-13-15 thanks for your input

I think you are pretty close, the only comparison i have is my friends 55Chevy with 4.1 toilet. It weighs 2650 lbs and it's 396" s/blk with 23 degree heads. he has larger tires 33X15X15, but a 4.86 gear, his 60' is a little better with 1.22 and it runs 5.62 @ 118, converted that would be 8.92 @ 146, he runs 34 degrees and 5500 converter. Twin Cities hasn't had a 1/4mi race since the car went back together,so i can't on 1/4 times.
