I don't know if my particular application will help you much, since these are completely different chassis, but I will be glad to help you all I can.....
In the v6 conversion, there were some probs with the crossmember, which took a wee bit of altering to fix.... In hindsight, it's a live and learn type of thing, which I might have been able to avoid, knowing what I now know, but it didn't affect the performance of the car at all, so it's ok...
As for the 350, the crossmember was NOT altered, believe it or not, and the 350 fits beautifully in to the car. Unfortunately, I do not have any pics from the "in the process" period. Lack of foresight.
I can't tell you whether or not the 350 would fall in to place in your car or not... especially without taking a stroll around it and getting a good look at it and taking some measurements. However, even if the oil pan DOES get in the way, there are ways to fix that. One, you can use an aftermarket oil pan, there are many available since the 350 is used so widely in street rod conversions. I have even seen instances where 350's were switched to be front sump, to avoid clearance issues. Also, if you are pretty handy, you could take off your oil pan, cut it, and custom reshape it to allow it to fit, if this becomes necessary. Thing is, there are many remedies... one just has to look at their particular application and see what needs to be done and what will work best in the long run....
And don't worry about the "pikedream" statements.... I got plenty of those too when I was building my '68! LOL! ESPECIALLY from my dad. It used to be his car, and he was NOT at ALL happy with my conversion idea.... infact, he threw a fit... I HONESTLY had to hide the car from him while the conversions were being done because he was sooooooo against it.... BUT...... after it was done, and he'd taken it for a drive (spinning the tires at every start and every corner), he was thorougly impressed! After his first test drive of the car, his exact words were: "Son, that's the best thing that car could have ever had done to it"..... I think that's the best comment my dad ever gave me.... I suspect if you do a good job, your dad will say something very similar....
Anyway, here is my post about many of my conversions.... check it out.
(w108) Non-stock Mercedes wheels and tires, oh and motor too! lol
Before starting this process, do what I did and check weights, HP and torque specifications, etc., etc., as I have listed in my post. It will give a better idea of what problems you may or may not run in to, and will also let you know things you need to do to correctly complete the conversion.
Another good idea... take your car to a scale... say like a trucking scale, and weigh it now as it is. When the retrofit is complete, take it back and weigh it again. It is very likely that you will have to have custom springs built for the front end. By knowing the stock weight of the car, and the retrofitted weight of the car, it will make a spring shop's task simple to retrofit you with a new set of springs....
Also, check the transmission and rear end gear ratios of the particular car you have, vs the typicl transmission & rear end ratios of the types of cars that the motor you chose would typically be installed in. Make sure that the rear end is not geared too high or too low for your application.... With my '68, the chevy motor/transmission did not mesh well with the Mercedes rear end which is why we pulled it and replaced it with a vette rear end. But in the '67, it still uses the Mercedes transmission and rear end, which work well together.
And don't let anyone TELL you that a 350 won't fit in your car... that's not entirely true, more than likely (I had so many people tell me that very same thing.... go figure! lol!)....... But if by chance it turns out that it won't fit, I know someone who can tell you how to convert a 108 chassis to sport a 350 if you would like to do that...
