I am facing the same issue right now with my son's car. The I6 is cheap on gas and is what the car has/came with... However, looking at the cost of rebuilding the engine, parts and machine work are at least the same, and often more expensive than a 302 build. If it wasn't for you needing all the conversion parts to install a 302, I'd tell you to go v8. The build will be the same, if not cheaper from what I am seeing. Once you add in the parts to convert to a v8 though, you gotta figure on rebuilding the I6. My son is working on a Fox body, so I6 to V8 is a cheaper stretch for us. That is why I am stuck. I6 rebuilds are more expensive than I would have imagined.
Find and install a 250 in-line six. Have your friend rebuild it with flat top pistons and a mild (smooth idle) cam. Have him mill the intake log for a flat 2bbl adapter and mount a Ford 2 bbl on it like this:
What other changes will have to be made going from a 200 to a 250? I have a rough list of changes for 200 to 302, but I'm assuming the 250 won't just drop in Thanks for the idea, though, I'd only considered staying the same, or jumping to a 302. Rhonda
Nope the 250 won't just drop in. If you are going to stick with a I6 your going to be better off staying with the 200 price wise. Two things I can think of off the top of my head you need to go from a 200 to a 250 is a bellhousing and a radiator. If I remember correctly the inlet and outlet on the radiator for a 250 is the same as a 302 and I know for a fact that the 250 uses a 302 bellhousing and the 200 doesn't.
Yeah, I think that the 200 is a small block I6 and the 250 is a big block I6. I don't think that they are the same block. Are the intake and exhaust even on the same sides as one another? I think on the 250 it is on the d. side and the 200 on the pass. side.
The intakes are cast in to the heads, the heads interchange on to the 144,170, and 200. The block was changed slightly for the added stroke. All the same "small block sixes".
I think I would try to find out what happaned to the motor thats in it, the pop was probadly a backfire that bluw out the hose, could be a timing issue as I see that has been reworked recently,it doesn't sound to me like the rings were reason it died, not sure how good the motor was before but fixing it could be your best(cheapest) way to go
Well, in the past week, I've driven from TX to NC with the DIL and grandbaby, deposited them with son at new duty station, drove back, and have not checked the mav. My husband was home for a few days,(of course, while I was gone) and checked it out for me. Said it is not getting any fire at all, the distributor isn't moving at all. I know there's a shear pin or key in there. It doesn't look like it's sheared. Distributor bad? I know a few days before it quit, it felt "not right". Like the timing was just a hair off. I can't explain it, I just know what it sounded and felt like. What about vacuum advance? Remember, within a few weeks of it going down, I replaced the valve cover gasket, timing gear/chain, alternator, starter, voltage regulator, and oil pan gasket. Ran like a champ for about 2-3 weeks. then, boom. Daughter called home from her mission trip the other night. All the way from Amman, Jordan, she wants to know if the mav is running yet. I guess I can't complain too much, I started this! Rhonda
you need to pull the distrubtor and inspect the gear if it looks good then get somebody to help you. you need to have them crank the motor over while your looking down the hole for the distrubtor. you should see the gear that drives it turn and should see all the teeth on it.
Rhonda Before you remove the distruibutor remove the valve cover turn the engine over with the starter and see if all the rocker arms are moving ?? If the frount ones are moving and the rear ones are not you broke a cam time for a new engine .. Jay
Since the timing chain and gear were replaced recently I would suspect that as the culprit. Maybe the cam gear broke loose or the dowel broke. clint
Well, sure glad that cold front came through. It only hit 99, instead of the 105 like yesterday! I took the valve cover off, tried turning it over, and nothing is moving. I'm assuming that means either the timing chain slipped or broke? After work tomorrow, I'll start taking it apart again. Is this common, or out of the ordinary? I guess I'll know what it is when I get the timing cover off. Unfortunately, it's parked over about 37 fire ant beds. I think my feet are swelling up!! Makes is hard to turn a wrench when you have to keep moving your feet. Good thing we live in the country, and there's no one around to see what that must have looked like Rhonda
Rhonda Looks like a trip is needed to the farm supply store for some fire ant KILLER and due away with the little sob. Jay
sounds like the chain/gear...good luck... ...and i find that a cup of gas works wonders on them ant hills... ......
