700hp 493 build specs thoughts

68 HEMI GTS said
I’m getting ready to re-assemble my 400/499 kit. That being said, the 400/512 kits are generally a better way to go. More CD on the piston. Plus I like the smaller Chevy rods. Rod ratio on those kits is still ok, same as a 454 Chevy. I sure wouldn’t bother with a 499 kit anymore, it would be 470 or 512. I think you may be able to get trick on the 499’s and get a better CD but they are not sold as a kit. Atleast as far as I know. 440-1 would be my head choice. Your cam specs look like Andy F’s 470 cam? If so I actually run that cam in a 512. It has pretty wild ramps, wouldn’t recommend it for a lot of street use. Of course I’ve been driving mine around.. lol

Noted, personally I did mention about a 470 or 512 more so on the 512 when talking about it all but not my money, I think the 496 kit has been ordered. I don't know exactly how much street driving its going to get, perhaps 30/70 race?..its only out to approx 4>5 meetings a year that may change.
Theirs still a lot of street influence here hence the comp and cam lift of .660 he was talking about, to him thats a big cam and he did mention that perhaps less cam as well so I don't know. I quoted the duration after Andy said that as the 270's have good low lift flow anything much more would not be beneficial, I'm going to try and suggest the 1.6 rockers to get it to .704" but think I'm going to fail there miserably.
So do you think this could reach the 700hp mark with a [email protected] .660 s/roller, 10.9:1 pump V-power and the 270's an Indy intake and a big 4150? one of our Mopar racers who builds a lot of these 493/496/499 motors reckons easy 700, I'm not so sure its that easy, thats quite a mild combo for my liking and that hp but then I haven't got to drive it on the street. At the end of the day this a brkt car but he wants to go from 11.0's with the 440 to at least 10.40's which it will do but thats a lot of money to go just .6 quicker in my book if it doesn't make the hp.
