If you aren't experiencing detonation then I don't know how you could be hurting the engine. Run the 87 but if you hear it detonating switch back to premium. Or mix it half and half if you want to feel better about it.

Some people just don't like dealing with headers. Spark plug access,burnt wires,leaking gaskets (flange and collector),and poor ground clearance with some header designs. They just want to get in and drive without the little hassles. I get it. If I had to choose between a good set of heads or a...

Are you having a cam ground for manifolds or planning to switch to headers later?

The better the cyl head the easier it is to make power. A good set of heads with something like the comp XE274 or similar would work. A hyd flat tappet with the same figures will get you there with stock rockers and valve covers.

You are blessed (and smart too!). I would still be waiting for a tow and hating life. :lol:

I wish you all the success in the world with it! My first car was a 73 Charger and I would love to clone it. Don't see it happening but a man can dream!

Big improvement with the scoop.The black grill doesn't bother me at all. Gives it a meaner,Darth Vader look IMO.

I would want to know what gear,converter stall,and vehicle weight before I comment. My guess would be trying to get the cam to come in sooner in a heavier car with a motor that is not known for bottom end torque.

I would go with the magnum one. Should be red for 69 I believe? Does your car have factory exhaust manifolds? If so are they HP or log? HP would have been a magnum and log style would have been four barrel IMO.

Techron and seafoam are good additives IMO and have been for years. I wouldn't have a problem using Lucas either. BG 44k has a good reputation and we used it quite a bit at the shop I work at until their rep disappeared.

600hp is doable with enough compression,head flow,and camshaft. While it is at the upper end of streetability it is doable. A performer rpm will support that and if it is ported even better. Something like trick flow or well ported Edelbrock heads will get you there. 10.5-1 and a cam in the...

Before I comment on intake selection I would want to know the rest of the engine setup , Cam,compression,heads,etc as well as the rear gear and what stall the converter is. That being said it is hard to beat a performer rpm intake for most street cars (especially a heavy one).

You might get away with a street dominator intake but I highly doubt a track heat or any other tall intake will clear.Maybe a performer rpm intake with a drop base air filter and a short air cleaner. Years ago I cut a hole in a stock flat hood and used a bolt on (riveted) six pak scoop on mine...

Congrats sir!

If that is the case then stick it in the lean side to monitor first. You can always install bungs in both exhaust pipes and switch the sensor to watch both sides one at a time if you don't want to spring for the dual setup. Install it where you have easy access for the sensor and wiring.Make...

Here is a 451 build to show you the potential. Built with quality components it will outlast the miles you ever put on the car with routine maintenance. A smaller cam will change the power but as you can see it is very capable. Street 451

You can still use the rockers just get a smaller cam. Mill the heads a little if you want some more compression. Just the flow increase alone will make more power everywhere. Just don't over cam it. I just pulled an 8.5-1 440 with the Comp XE274 out of my Duster. Changed from stock 452 heads...

That cam would be a bit tamer in a motor with a 4.15 or 4.25 stroke. Still rowdy mind you but more manageable. I ran a 246* intake @ .050 hyd with a 3.91 stroke and my power brakes were fine. One size smaller would be manageable but two sizes would be better matched to a cruiser and still...

FWIW I bought a street fighter trans probably around 2000 or so and put behind my 496 in a heavy C body. Took a beating and was still in the car when I sold it in 2020 or so.

The slug 400 on the dyno.
