Big Block Brainstorming

I have a 454 that I pulled out of my 70 Chevelle and I've be considering swapping it into a 94 mustang v6 i planned to flip to make it a drag car. Id make my chevelle more street oriented and probably swap in a tko600 to use the th400 i built for mustang. As far as im concerned this motor should be pretty fresh with potentially a forged rotating assembly... I'd verify all of this first but it did run a 12.77 in the 70 chevelle with a small hyd roller, 063 heads, edelbrock performer rpm air gap, 650 cfm double pumper and the th400 with a very tight 2000ish converter. Would anyone have a solid roller cam recommendation for this motor? I'm wondering if i could get enough out of this set up with just a cam or maybe piston swap also to increase the compression. Since the mustang is close to 1000lbs lighter I think it could make a pretty fun track car. Thanks for the input.

Re: Big Block Brainstorming

Drag cars are hard to sell. I hope you don't have much money in the Mustang and the 454.

Re: Big Block Brainstorming

I thought about doing the same thing with some extra 454's I have but I was going to use a 99-03 Mustang. Sure as hell am not going to use a 4th gen Camaro for this as it's a nightmare to get stuff to work in those old Camaro's and the rear end is made of glass. The only drawback would be making some headers so I guess the tig welder will need to be used for that along with a good turbo 400.

Re: Big Block Brainstorming

I donít know about where you live, but around here, SF Bay Area, with a little patience and some effort you can find a competitive turn key 10 second bracket car for $10,000-15,000, considerably less you you are looking for grudge night or T&T bomber. It doesnít make sense to build something from scratch unless you have a sentimental attachment.

850 Carb

get compression to at least 12.5 to 1
Solid roller camshaft and lifters
With the untouched 063 should be able to get very close to 600HP and 560#ft. In the stang that should put you in the 10's with some suspension mods.

Why is it we never have time or money to do it the right way in the beginning but we always have time and money to do it over again?

Re: Big Block Brainstorming

Why doesn't the OP just build a streetable 454/468 with 550-600 HP, rebuild the TH400 to handle the power, and go with 3.31 gears....IN THE CHEVELLE?

That's a high ten/low eleven second car that could be driven to the track....with mild manners.
