Mainly a street car. I work in Norwalk OH, so will it go down the track from time to time.

That sounds like the best way to do it. Having the rear of the car up would have probably made it easier. Thank you for the compliment on the Dart!

I made a few modifications to the inner fenders and spark plug changes shouldn't be an issue. Stroked small blocks are nice, but you will never get the the HP and TQ numbers that a stroker big block can produce without spending a fortune or having an engine that is more of a race set up. (i.e...

Thanks!

Well, installed my 470 Low Deck for the final time in my 68 Dart and tried we tried a different approach. The engine was in the car before for mock up, but didn't have headers at the time. The engine went in pretty easy for mock up, but we decided to try bolting on the headers and transmission...

I just purchased the 3" kit for my 68 Dart after seeing this thread. Kit came within 2 days of ordering it and looks pretty good. The 3" system actually does have the X pipe shown in their photos, but will require a little work as there is still only a small hole going between the two tubes...

We only made two pulls due to the AFR issue. I was just on the dyno to check for leaks and run in. The carb used was a 950 HP dyno carb and I am going to run sniper xflow fuel injection in the car and will do more testing in the car on a chassis dyno when the car is all together. I agree that...

You can make great power with a 470 (400 with 3.91 stroke) and the question becomes, how much HP and TQ do you need for a "street" car. I just dynoed my 470 and it had 658HP and 689TQ. It is going to be hard to get it to hook up on the street with that much TQ as it is, but will be a lot of...

Thanks Andy! That makes sense. What about the shielding the sniper wiring? Have you done that on any build in the past?

Yes, wiring is one of my biggest concerns. The fact that the wires for the sniper unit come out the front side near the distributor where are all the plug wires run causes me some concern. I am going to run Firecore spark plugs wires and try to route the sniper wires as far away from them as I...

Hello Andy, I have read a number of your posts and found them very interesting. (including your Duster build) I am currently installing a fairly stout 470 low deck in a street/strip 68 Dart. I have the Holley Sniper X Flow + the Hyperspark combination, but this will be my first time going with...

Thank you for the info!

Have you had any issues with the wood spacer warping? Do you change it every year, or have you run the same wood spacer?

Good question. I am not running the spacer for HP as much as I am running fuel injection and the spacer apparently reduces noise from the injectors that is common with the sniper systems.

Hello, I am looking to run a 4 hole tapered spacer on my 470 and had a question for the group in regards to phenolic vs aluminum carb spacers. I was looking at a Jegs phenolic spacer that says it is good with temperatures up to 400 degrees, which seems to be pretty high. This is going on a...

Thanks everyone for all of the info and picture! On my dad's 68 Coronet we used the square tubing style so it was little different and that was year ago. I have the full core support and the inner fender braces and boxed shock towers as I'm going to be running coilovers in the front instead of...

Looking to see if anyone has experience installing the US Car Tool torque boxes and subframe connectors. My questions is, do you stitch weld the subframe connectors to the floor pan, or completely weld them? I think the torque boxes would get weld completely, but the subframe connectors would...

Thought I would share some pictures as I recent mocked up the 22" Cold Case Radiator in my 68 Dart with a big block. I am running an electric water pump in a factory style aluminum housing and the fans and shroud were made to make it fit. (I tried a single 16" electric fan to start with, but...

I am going to be running the Cold Case 22" with dual SPAL fans in my 68 dart with a 470. I have only mocked it up to this point in the below pictures. My dad used the 22" Griffin 1.25" Tube Size 2 row in his Coronet with a 493 and it works well. It will be a tight fit with either one in an A...

Here is a picture of what was originally in it.

Thanks for clarifying......Sorry if I confused anyone as I saw that I wrote "Main Cap" above.

He had a number of them there, so I believe he was able to match one up.

Yes, he replaced the aftermarket billet rear main cap I had on the engine with a stock type and used fel pro rear seal P/N 2947. We talked about this quite a bit and he said they have had the best luck with the stock style rear cap and this P/N rear main seal as the aftermarket billet caps have...

Yes, you are correct. I have the sniper XFlow system with 4 ea 120 lb injectors that will be the final setup. I’ll tune the motor in the car with the final setup and make sure it has more fuel. Since it wasn’t my final setup, we just made the two pulls and didn’t play with the fuel or timing...

Will do.

No problem. Hopefully the info helps someone looking to build something like it in the future.

Yes, this is a function of the Cam and intake manifold I believe. Neither is optimal if I wanted Max HP numbers, but the intake allows me to run the stock hood and the Cam is making great power and torque for a street engine. Also, with the HP falling off at 5,500 I won't have to rev the...

Yes.....I was really happy with the numbers. Can't wait to get the car put back together and go for a drive in the spring! I wish you luck on your 470!

It was really cold this morning, but probably helped the numbers a little. It took a long time to get the motor even up to 140.

Update...........
