In 1977, the HP engine was actually lower compression than the standard engine at 7.8:1 according to my service manual. The heavy duty piston had a lower pin height than the standard, for whatever reason, maybe emissions? The ID pad on the block and partial VIN should tell you everything you...

The general wisdom is that the HP is meaningless to the block, aside from telling the original application the engine was used in and what kind of internals it was equipped with stock. Now, actual heavy truck application blocks and heads are supposed to have larger coolant passages, but I don't...

According to the passenger car manual, T could just mean it's a Trenton engine, unless that's included in the"7T". It could've been out of a truck, but the T doesn't necessitate it apparently. Interestingly, mopar did offer truck and van police packages in 1977 and 78, and 440s were...

I'm building this engine for a friend and I've never seen a block stamped like this. It's a 1977 630 block cast 9-18-76 but there's no VIN or serial stamped anywhere on the engine, pan rail or starter pad. The top ID pad has what looks like a faint HP or maybe HP1 stamped under the 7T440T...

No K in vin and no A38 on the fender tag means it's most likely a taxi or just a car somebody ordered for a business that needed an accurate speedometer. It has a roof light reinforcement so it may have holes in the roof for the light, the zipper could be a repair where they cut the headliner to...

I did all 4 of mine on the ground with jack stands in about 3 hours. Most of that time was spent drinking beer though.

My Gran Fury has this engine, the E68 is the high performance/heavy duty version of the E64 4bbl which was the most common engine for non-police applications. In 1977 and 78 the E68 was equipped with lean burn and single exhaust with a catalytic converter as standard, unlike previous iterations...

Those models were discontinued in 1977. No C-body cop cars for 1978 unless they got a Newport (believe it or not a few departments ordered those.) My '77 parts book lists a 15x6.5" as the heavy duty wheel. "Police Wheels" with the rally slots weren't even a thing until 1978, before that they...

It's more than likely not lead. Most quality leaded fuels contained dichlorethane or dibromoethane to form lead chloride or bromide salts which leave the engine with the exhaust to prevent this very problem with metallic lead fouling in the oil and plugs. Either someone burned lots of very poor...

Have you tried using a stock 100A Leece-Neville alternator? Also, you need to ground the alternator and every other powered component on the vehicle with a cable as large as the hot wire as even an ohm or two between the alt and the engine bracket will cause nearly all current to be put through...

I had this problem manifest on my 400. The pump worked initially and lasted about 6 months and 1200 miles. One day I was sitting at a light and the belt started squealing because the pump locked up. The impeller was already very close to the pump housing and walking back a few thousandths from...

Here are the torque boxes at the leaf springs on a 1981 R body A38, they appear much more substantial since the frame is narrower on it

Here are some pictures of the mentioned areas on my car, it's a 77 PH41 A38. I didn't see anything directly behind the upper control arms, but there's a hollow box where the frame meets the firewall with some metal gussets on it. Also one at the front leaf spring hanger. The rear hanger has what...

I've installed 2 cheap aluminum radiators that did not fit at all, but with a little grafting and fabricating they fit and work. I put a radiator for a mustang in my slant 6 Aspen and a radiator for a b-body in my c-body Gran Fury and all it took was some metal plates to connect the flange to...

And of course as soon as I got to Mopars at the Rock today it let me down. It looks like the well plugs fell out and flooded my motor out when I cut the car off after pulling in the gate. I used JB tank weld on them when I built it about a year ago and it decided to let go. I had a spare Holley...
