Just in case.....it's also a good idea to hone with deck plates to simulate any bore distortion that the head bolts may cause when assembled. Some people go so far as to use the same head gasket that goes into final assembly as well as bolt on a head or deck plate on the other side and...

Agreed! I've gotten at least a tenth better performance going from a 3310 750 vacuum secondary to a 4779 double pumper after spending time tuning both on the same combo.

Regardless of brand, many people leave out the front & rear end gaskets and just use silicone. Some end gaskets squeeze out and others are too thick or hard and don't let the intake sit low enough. Make sure the intake lines up properly with the side gaskets in place. Depending on any other...

It depends. One has to determine what .15 seconds in the 1/4 is worth - what it takes to achieve it and what it actually costs in time and money. A lot of the "worth" depends on the rules you race under. The more restrictive the rules are, the more difficult it is to make "legal" changes for a...

The best info I've heard was from testing Chrysler did between a 727 and 904 in the '70's. With both transmissions and their respective converters built to the same specs and the vehicle weight adjusted for the different transmission weights, the 904 was about .15 seconds faster in the 1/4 mile...

OEM cars are usually built with compromises leaning towards "street manners", not meant to be "beat on" and with "comfortable" shifts. But there are different "duty" levels of transmissions. (i.e.: 904, 998, 999) I've always heard that heat is the most common cause of transmission failures...

I ran JW Trans. built 904s in my Dart for years without any trans parts breaking due to outright fatigue. The few trans failures I've had were due to driveline failures first resulting in broken sprag or broken trans cases. Best numbers 11.14 @ 117 with 1.47 60' @ 3,540 lbs footbraking. Usually...

The round, raised area in the middle of the axle flange that the hole in the middle of the brake drum fits over. 4" bolt pattern Mopar axles have a smaller register.

1971 Dodge Dart short track race car This is the closest I could find. Don't know if it would be possible to contact the builder for info, leads or ideas.

Did Chrysler ever produce any "dealer promo" models of a Valiant? I've had Dart Sports & seen several other of the "sportier" models. Was it MPC who produced them? Try contacting some of the remaining model manufacturers? There were some Japanese model companies as well. I have a '72 or '73(?)...

Brand of shifter would be a start but even they could vary between models of shifter. Obviously you need one for a 904 but both you and the seller has to know if a particular bracket is for a 904 or a different brand of transmission. I believe Hurst is under the Holley banner and Summit...

I believe the originals took a socket to remove. I don't recall the size off-hand but it was a pain because there wasn't much For the socket to grab on to. The internal 3/8" drive was a welcome change.

340 cast crank engines were externally balanced also. But I don't know the size or weights of the weights used. A 340 cast crank definitely had less external weight on the converter and the balancer than a 360, so they will not interchange. I believe 340's went to cast cranks some time during...

I used a 360 with Holley Strip Dominator, unported LAX heads, around 255*@.050 flat tappet cam in a 3,540+ lb car. BUT.....it had 4.86 gears, 30x9" tires and a converter that actually flashed to 4900-5400 rpm, depending on the weather. Footbraked from 3-3500 rpm, stayed well above flash thru the...

Looks like a Milodon small block. But you'll have to determine the part # based on the sump depth of the pan being used. If the pan is not Milodon, you'll have to do some careful measuring as they have 5 qt. (OEM), 7 qt. & 8 qt. pans with center (front) sumps & check internal clearances. At...

You can also consider Prothane 4-801-BL for 7/8" applications. They are made out of polyurethane, firmer and more durable than plain Chinese rubber. Summit has 1" also. For Moog, confirm the quantity you get. It seems like some listings aren't clear on that.

I wouldn't change the shackle orientation. If ever needed, I believe it's possible to slide the shackle out without removing the frame mounted hanger. Front hanger nut is on the inside also. Frame gets in the way with the nut facing out. I also recall seeing SS spring numbers stamped on the...

1978 was the last year for OEM Mopar big blocks!

RAS installs bushings in the rockers using the original bore and adds smaller diameter shafts with thicker walls. I believe they correct the individual ratios in the process and include new 12 point adjusters and hold-downs in their package deal. Bushings are drilled and/or blocked in the rocker...

I can offer a few bits of info but I never got Thermoquads figured out for my purposes. The 9811 is an aftermarket performance version that wasn't available as OEM on any cars or trucks. That "family" includes 9800, 9801, 9810 & 9811. Depending on the overall condition, that may be the best one...

I've had crank bolts leave impressions through paint on the converter but no dents in the converter unless I had a major driveline breakage. Clearance is tight. However, that doesn't look like an OEM crank bolt and they definitely don't come with washers.

It's easy to tell if it's a lock-up trans/converter. May have to get inside to confirm if it has the 2.74 low gear set. I don't think a lock-up will automatically :p have a low gear set but I'm not sure. Lock-ups started in the late '70's. JW Trans. in Rockledge, FL built my regular 904s with...

I always rotated my Hoosier 9" Lightweight radial slicks after every weekend. Pretty much eliminated uneven wear, longer life till the wear holes started disappearing and gave me a chance to check rear drum brake adjustment among other things. I don't know if tire type. air pressure or...

Dart Sport will work. Regular Dodge Dart (i.e.: Swinger, Valiant, etc.) window contours are different than Duster/Demon/Dart Sport and won't fit the roof/a-pillar shape. 1973 doors have unique window mounting locations inside so if you need to replace the glass, you'll need 1973 glass. 1973...

I tried Mopar stick drag shocks but they were still too soft for my auto combo. The harder a car leaves, the stiffer the shocks should be to control separation & wheel-hop, even with SS springs. I ended up going to Rancho myself. Ranchos use to be 3 or 5 way. Now they are 9-way. I don't have the...
