I would build a 67 Nova,use a tci 6 speed,4.30 gears.
The engine would be 4.185 bore x 3.62 stroke. I would use dart 227 heads 111313-12 NA 279 279 247 247 .585 .585 112 108 .022 .022 1,2,5 2800-7400 Fair idle, Pro-Street cam. Works well with small NOS system. that cam 850 holley on a victor Jr step headers |

Providing the model of car you're using, and whether or not it's to be street-driven would be really helpful... We have a 406 in a GMC pickup that [only] goes 12.20s... Put it in a 3,400 lb. car, and it's a SOLID 11 second machine... See?

Thinking something more simple, and in a 55 Chevy around 3300 pounds 4 speed and a pretty good driver.

So same pistons and rods etc? I'm thinking a 406, 95:1 cr, 215 dart pro 1's or profiler 210's, a hyd flat tappet or roller, 1 3/4 long tubes, Vic Jr or rpm air gap, 750 demon. Keep it simple and something that works. 3.55's 3.73 maybe even 4.10's. Muncie 4 speed, traction master Trac bars, and some 29x10.5x15 Hoosier qtp.

If you are going to use tall 29" tires get 4.10's or 4.30 gears. Get a solid lifter cam.
Like a Isky 201534 or a Comp 294-S magnum For a 55 Chevy it needs a Edelbrock Tunnel Ram and 2 750 edelbrocks. Last edited by F-BIRD'88; 02-28-2013 at 01:52 PM. |

I have both edelbrock and wieand tunnel ram I also have the isky 201549 cam new in the box. I want to stay alway from solids though, I don't want to be adjusting valves all the time.

Use them. Set the lash on the Isky cam Cold at .014"in and .016" exhaust COLD. using the IC EO method. Set and forget for 3 months of street driving. Nothing hard about that. Get a grip..... you already have the right parts, use them. For the Isky cam and street pump gas get the compression ratio up between 10:1 and 10.5:1. With a tall 29" tire use a 4.30 or 4.56:1 gear with the 4 speed. DO you want to go 11's or pretend to go 11's? Last edited by F-BIRD'88; 02-28-2013 at 02:38 PM. |

Actually I got the idea from one of the other 400 builds you recommend that cam, cause I had got pistons and rods, but it turns out the pistons were too high cr for the street. So 400 is on a stand still, but I want to start back up on it again, cause I want to play on the street already and these new 5.0's are killer on the street. Being a 19 year old full time college student, makes it hard to save up for the turbo build I want to do :/ and unlike most of my friends my parents don't spoil me, I got a little paint & body shop that I just started up hopefully that takes off so I can fund my project's. 2 55's and a 66 elky. But I'm thinking tunnel ram is too much, I like maybe like a Holley strip dominator with that cam and a 750 Holley or demon, problay end up going with a 28 inch tall tire instead.

Getting something as heavy as a '55 Chevy into the 11 sec. range will take more work, and be less stretable. It can be done, but you'll need to go with something like F'bird '88 described. I had solid lifter cam in my BBC Camaro for many years, and rarely adjusted them sooner than 5,000 miles. The myth is that solids wont stay adjusted, but even without poly locks mine didn't unscrew themselves.

The tunnel ram is not too much and do not choke it down with small carbs.
650-750cfm x2. Still needs a 4.30-4.56 gear in it. Stop being a wimp. Girlie man. Turbos are for **** |
