hi has anyone any info on this motor conversion?
it must be probably one of the most common v8 conversions because of its simplicity.
planning a quick and painless conversion on my daily driver.
cheers

In terms of having one available it is likely worthwhile, tho from memory, the physical size is similar to that of a 308, which is FAR beneficial over a 253, and a 350 is smaller than both, which again is far beneficial.
engine mountings will bolt up in a similar fashion on 253 and 202(and smaller), tho the key is getting the motor as far back as possible.
My 350 does not mount using the side mounts, instead using somewhat custom front mountings.
In the wise words of Merlin, "if you want it to rev, put in a chev"

.......... "quick" ??? ??? ??? .. "painless" .. ??? ??? ??? there is no such words in the bugawegian vocabulary, ben! ;D ;D ;D ;D ;)

I put a 253 into my last van. It took up quite a lot of space and I took more so I could get my hands around the motor for easier maintenance.
To overcome this problem and to leave room for my left foot I only cut floor and bulkhead from the passenger side and mounted the donk left of center and on a slight angle.
Other than moving the engine and gearbox mounts this created no problems at all.
The sound was awesome, ( at low revs it used to set off car alarms ;D )but I did find I like the smoothness of a six better, but at least I can now say "I have owned a V8"
-
Jeff thats interesting, ive never thought of that . its a great idea.
how far off centre to the left was the motor mounted?
cheers marty
-
I really don't remember, but about 2-3 inches, and the left one moved back to the edge of the crossmember.
I lined up the gearbox to split the misalignment with both universals.
-
253 and 308 are the same size only difference is the bore size 308 and 350 are both 90 degree v and very simmilar in size 350 slightly smaller across the heads we have a chev in ours plenty of feet room goes like stink and is mounted central
-
jeff ... what did it drive like ? would the diff need moving over ?

jeff ... what did it drive like ? would the diff need moving over ?
The van drove smooth and normal on a std 9 inch diff.
The angle of the drive shaft was no worse than the angle of the normal up and down movement you get with an empty or heavily loaded van, or on a bumpy road. Except this deflection was horizontal instead of vertical.
Universal joints require some misalignment for the rollers to move and so the wear is not taken on only one spot.
-
yeh im not interested in moving the mounts this time around. its my daily driver and ill need back on the road asap..

can send u pics of my set up an floor cutout, if u so desire ben ...just let us know......... ;)

Ben
I currently have 173 and 253 Beddy's in my drive so I took these photos to show the floor fitting on the V8
and also compare the 6 vs 8 engine mounts
Hope it is useful

can you use the 202 engine mounts for a 350 ??
i ask this as i have a 202 in my 79 van and a 350 in my 73 parts van
i was planing to just roll one out and the other in but if its mounts up should i use the newer cross member ?
i saw a add on trade me that made me think ...

""the front end has the hq disc brakes and is set up for a 350 chev but has a 202 holden in it at the moment have drive shafts for her the rear diff is an old bedford diff just so it can be moved "" ???
-
202 to 253 or 308 yes but 350 Chev I would have to say no, but I may be wrong.
-
thats what i thought stil i was the trade me add ... :)
-
You may have to do a measure then, I would roll the whole cross member under.
-
engine mounts look to be in similar positions on 202 and 350 blocks.. however the reason he could put a 202 in a van that HAD a 350 in it, is that the hole has been cut to suit a 350, then just put a 202 back in.
To put a 350 in a van that has never had a 350 requires more effort
-
but is it an easy fit as far as the mounts go
i am going to fit the 350 and 400 trans anyway
cutting the hole isnt a worry
i know just taking the cross member out the lwb with chev and trans and rolling it under the swb
is the any difference in the cross members ? apart from two towing eyes ?
-
Everything is interchangeable, as I have done this from a SWB parts too a LWB Duel front end. still have my doubts on the mounts, even from a 202 to a 308 can be problems depending on how the mounts fit on the cross member, eg. to far back or forward etc.
-
aside from cutting the bigger hole, the only problem i can see if you swap complete chassis, is that the tailshaft will be the wrong length, tho this is easily fixed.
-
The driveshaft is no good anyway, as I understand it is from a LWB and if it is going into a SWB it,s the wrong length anyway, but as you said this is no big deal to put right. I would swap front ends and enterchange the best parts, will need to use the whole Hub or disk with arms etc as there is a difference in size.
-
the drive shaft is a two piece on the lwb .. will be getting the ends put on to the swb shaft
the 10 bolt rear is to be swaped soon needs a small mod (lwb has shocks on inside of rail ,swb is on outside)
not sure if thats a lwb/swb thing or and age thing
i thing swaping the front end over will be best as its running hq disks

why this has a 202 in it instead of the 355 its used run back in the day was due to the previous owner gutted it of the drive train and the new owner (wraithknight on here) all he could get his hands on at the time for a power plant for it was a 202 not sure how he has mounted it up but i can try to find out

all good mate, had to work on saturday n spent sunday trying to get the dash finished off, no luck on the studs as yet as i didnt get the right size easy out so it'll be another trip to mitre 10 for a couple more of them. sounds good if you've got a couple of hours to spare
Scott
-
no worries mate will ring ya tomorrow, and we can get some more things crossed off the to do list.
Cheers Jeff
-
cross lots off and drive it up ... want to see the rb conversion :D
-
slowly starting to tick things off the list, after a discussion with jeff today we worked out itys less than ten things to get it driving and wof'able
so fingers crossed it dont take too long to get it there.

as to the 202/350 mounts question, i spoke with the owner today and he said that he just used the 350 mounts that were on the crossmember to mount the 202 to, and he said it was fairly straight forward n easy. hope that helps out
Scott
-
thanks scott ...
think ill just swap the hole front end with the hq disk ...
my 10 bolt rear is going in in the week end hope the 202/5speed will cope with it lol
