I`m looking at a crate motor for my 67 RS/SS. I curently run a standard 350/220hp slug. I`m looking at a 383/450HP crate motor, is there any thing other than brakes that I should consider doing to the car before I drop this sort of HP in. The car is standard with only disks on the front.

Has any one got any idea what sort of quater mile ET this combo should deliver.??

I apprecate any feedback.

I would get some sub-frame connectors. I've got about 550 H.P. and used to launch this car hard without them. Sanding on the car this week I had to go down to metal on 3 paint jobs to get the stress cracks out. They were really bad around the rear quarter window & sail panel area. And I pulled the passenger door to see what I can do to get it to open & close right. I noticed a small tear at the lower hinge in the door.

Brakes are a very good idea, but I would stiffen the chassis up a bit. I'm still not sure at what H.P. level the bodies start to flex, but I have noticed movement on mine, though not bad.

even with a low performance V8 the subframce connectors will make a noticible difference in both weight transfer and handling. I have a '68 with a standard 327/210 horse (soon to be something else) engine and putting in the subframe connectors helped my traction problem considerably. It also seems to handle better in the turns.

I agree. You could also consider a rear spring bushing upgrade and maybe even some sort of traction bar system.
On another note, what rear end is in the car and also what transmission are you planning to use. Depending on what type of use your car will see, you might want to look into those areas as well as the U-joints and J bolts that hold the rear end.
Sounds like you plan on having a fun driver. Good luck with it.

Thanks Guys

It`s got a standard 12 bolt with a standard TH350. If I do the transmition up and put a posi in the rear what is the maximum once a week streetable HP do you think I can go to.

Don't forget body bushings. You probably should go with solid ones. I have Global West aluminum ones. They don't add any noticeable harshness and will help lock everything together.
