Engine advice

Post  Inthegarage on September 16th 2015, 11:58 am

I have a 429 in a 52 Vicky with a C6 and 9" w/ Detroit locker............It is presently stock with a Performer 460 and 750 Holley...but I want to warm it up a little Smile... Just got a narrow rear housing so I can tub it...Can't get more than a street tire on it now....

Here's my questions..........What cam would be good for street/strip ?? Flat tappet or roller ?? What is the biggest valve that I can get in the DOVE-C heads ?? Where's the best place to find power ??

Any advice appreciated...............

I think the best place to find power will be on the exhaust side of your DOVE's. Loose the Performer intake also. If you are on a budget I would stay flat tappet. I would go 2.19 on intake valves.

I would think a 1.75" exhaust valve would seem to be best, but a lot of guys run a 1.71" and I think it is a more common valve for the big Fords. 13/4" to 17/8" header's with 21/2" to 3" pipes depending on your cam and vechicle weight and your objectives. I run 13/4" headers and 21/2" pipes on my warmed over 429 in a heavy truck to help the low end response and that combination performed very well for me.

I think they are very good for mild builds if you don't mild the weight, they also look stock to Chevy knuckleheads. Wink

I know this intake has been highly modified but, it goes to show the potential of the factory SCJ factory iron.
