old rat 49 Posted January 10, 2011 Report Posted January 10, 2011 Who has used a modern V6; 3.9 or 4.3 auto etc ? Quote
Barabbas Posted January 11, 2011 Report Posted January 11, 2011 Rat--I did some searching of old posts and found:http://www430.pair.com/p15d24/mopar_forum/showthread.php?t=8110&highlight=V6+swap. I was hoping that your question would get more response, a V6 seems like a good choice if someone wanted to do a swap Quote
bob westphal Posted January 11, 2011 Report Posted January 11, 2011 A GM V-6 would be an easier swap than a mouse motor. I had a 283 high performance in my P15 back in the early 60s. It was a tight fit and had to be set off to the right side of the car about 2" to clear the steering. In today's economy a more efficient engine makes sense when your looking for modern equipment in an old car. Bob Quote
james curl Posted January 11, 2011 Report Posted January 11, 2011 Check with Tim Adams as he has two early Plymouths with MoPar V-6 engines in them. Quote
Tim Keith Posted January 12, 2011 Report Posted January 12, 2011 An inline Toyota 7MGE six from a Supra has the same block profile as the original 218, although it weighs less (440 pounds). The head is much wider than a 218 but the Toyota block is the same size as the original flathead six. I have 2 business coupes, one without drive train. I'd consider the Toyota motor for the motorless bc as the Toyota five speed has hydraulic clutch that ought to be easy to work with, although I think the shifter might be in the wrong place - don't know about that. The transmission for the turbo models is very nice gearbox, the common Supra five speed is as well, but the turbo model gearbox is a step above the T5 - a short click to change gears . The common 7MGE only has 200 HP (the 7MGTE turbo had about 230) but its a long stroke motor with good torque. The motor is an underachiever stock, can be modified to make much more power. The bore is about the same as the Plymouth 218 (3.27") but the stroke is 3.58 inch (same as a Chrysler 360 V8 ). The 7MGE block is cast iron and dependable - as long as you retorque the head gasket. A new JDM motor ought to have a new head gasket and maybe ARP bolts installed. Remove the plastic cover and the 7MGE looks a lot like an old Jaguar six. It is long stroke but it will wind out to high RPM too. I love smooth inline sixes, always my choice over a paint shaker V6. Quote
PhilJohnson Posted January 12, 2011 Report Posted January 12, 2011 While not a V6 I did see a 151 Iron Duke in a 53 Cranbrook once. It fit pretty well. I wonder how well a Jeep 4.0 would fit under the hood? Plenty of horse power (190 hp) and it is pretty easy to work on. Quote
greg g Posted January 12, 2011 Report Posted January 12, 2011 jeep engines are 30 + inches long, so not a real good candidate. Quote
old rat 49 Posted January 12, 2011 Author Report Posted January 12, 2011 4.3 is 26 from water pump flangw to flywheel. 4 inches or so shorter than a 350. Whay would the length of our flatty be ? Quote
Tim Keith Posted January 13, 2011 Report Posted January 13, 2011 I have a GM 3300 90 degree V6 that is based on the 231 Buick V6. The 3300has a lower deck height so that it is not as wide, which could help with steering box clearance. The 3300 was only used in front drive applications. I am not sure what bell housing could be used with the 3300 for a P15. I think the 3300 is the same as GM 60 degree bell housings. The 3300 heads are the same as the 3800 series V6. Its only got about 160 HP, but its a good motor that is a little more compact. GM replaced the 3300 with a 60 degree V6 for use in smaller front drive cars. I generally prefer an inline six, but a V6 can work very well when space is an issue. Tim Quote
old rat 49 Posted January 13, 2011 Author Report Posted January 13, 2011 I'm leaning towards buying a late model Blazer doner. Driveshaft from a longer wheelbase and should work out about right. If the electronics proves to be a problem I think Edelbrock makes an intake. Have to do a some research on an S10 site or two. Really want to keep it lookinf stock on the outside and interior as much as I can, but need a fully functional modern drivetrain. Quote

What about the V6 Power Tech 3.7 from a Dakota/Durango or Jeep Liberty/Cherokee with either the 4 or 5 speed auto or even the 6 speed Gertag manual? 210HP with 235 Ft-Lbs Torque. Drive shaft should be long enough as well. Quote

Tim Keith Posted January 14, 2011 Report Posted January 14, 2011 The GM five cylinders can look retro, sort of, when the plastic covers are removed. Some like the inline fives, others don't. They're a relatively low cost option from a late model wreck that ought to fit where a 218 L-head once resided. The 4200 inline six is also good but it might have a little too much length without mods to the car. The inline needs a dummy flathead cover to fit in : http://image.classictrucks.com/f/8383387+w750+st0/0305CL_SHOWSTOPPER01z.jpg Quote
