I am in the process of tracking down a 292 and planning the build. I built a turbocharged 250 and it ran great until it exploded (literally), if I can figure out how, I will post pics.
Now that I have some experience with straight sixes, I would like to start playing with a 292, but have some questions first. Will a 250 head bolt onto a 292 block? Reason being I hand built an exhaust manifold and intake for the turbo application. I just want to know if I have to do that all over again. I read in another post that there is only 1.75 inches height difference and no length difference between them, is this true? When the motor exploded, something went up and hit the bottom of the hood, so some bodywork now has to get done, so I am thinking of a cowl induction hood.
That is all for now, I am sure that I will have some more questions later,
Thanks

Another question I had was how hard is it to fuel inject a 292? I really have no experience with FI, but am willing to invest the time and money, or would it be best to get it running and get all the bugs out of the new motor, then try a FI system. I realize that a new manifold would have to be built if it were to be a direct port type set up and the computer work, and electrical work could be "fun".
Any feedback would be great
Thanks
Rob
Yes the Head will bolt right up an the intake systems will also swap No Problem.My 2cents is work the motor bugs out Then FI it. this way Your only playing with one problem at a time. Right??
rob, i've done the f.i. and can steer you the way i did it. mine is multiport and has electronic timing control. now i have the bugs worked out. i will help you anyway i can. check out some of my old posts in the high perf section. tom
Here's a link to stovebolt.com and an excellent explanation on posting pics.
you need to get it hosted on the net, or your ISP may have provided space with your accoun, then link the address.

Believe me Larry, the last thing I want to do is grenade another motor. As it is the last one took over two years of R and D and cost in the neighbourhood of $6000. This time I will build a motor that should be able to handle the extra boost though.
Thanks for the info

What kind of vehicle did you have the motor in Rob? Your engine swap won't be too hard except the mount on the passenger side is in a different location. Also flywheel is different(larger bolts to hold it on) but all the manifolds are interchangeable. Keep us informed.
The vehicle is a 1964 Pontiac Acadian four door. A bit of a grandpa's car, but it was really different and unsuspecting. It moved pretty good for a mildly built motor and a relatively large, heavy car. Took a few people off guard, it was fun.
Another question that I had for anyone who could field it is about a Dry Sump Oild System. I heard that the original oil system on a 292 was not really all that good, but is a dry sump really necessary for a street motor that may see some track and dyno time?
Thaks for the help
Rob
On the 292, it may have either 7/16" or 1/2" flywheel bolts. I have had both.
A stock oil pump should be fine for a street and straight line motor. Add some baffles if you are going to be pulling some G's. I have a NA 292 in a drag car that sees 6600rpm with a stock pump and has no issues with oil pressure or distributor gears.
