Well it is time to build a new motor and I have 2 spare motors that I can use to build one good one. I have a H case they say I shouldn't use unless I add case savers and a no numbers case which I believe is a replacement case which looks to be pretty clean that I have had for several years just sitting in the shop. I will be cleaning them both and choose one to have vated after my builder inspects them both. I have a 1965 Velvet Green and Blue White Bus with stock transmission and would like to build a bone stock 1600 Singleport. Planning on going with a 30 pict carb, 205T Distributor, Dog house fan shroud, BOSCH alternator, complete NOS exhaust. with heat exchangers. All engine tins will be blasted and Low Gloss Black Powder Coated. Want to have that OG look. Here are just a few pics of what I am starting with, still full of grease gunk and oil but will be posting more pics as I clean and sort all parts for build. I know these cases are not correct for my bus and not going full purist but definitely reliable!!    Any suggestions appreciated.
More pics to come!! | |

| the unmarked case is probably a T3 case and the engine number will be stamped on top right side of the case- you can use it but make sure there is an oil pressure switch hole drilled and taped opposite the distributor hole. The h case is often maligned, but have used several with no problems. Their big issue is cracking above the #3 cylinder into the bell housing. DJ tested for that by removing the deep top rear head stud and spraying wd-40 in the hole and hitting it with air pressure while watching fo a mist of oil on the backside. So clean them up have the guy look them over and get back to us. opinion untempered by fact is ignorance. Don't step in any! | |

| I looked on the right side but did not see any numbers and will look again for the oil pressure switch hole did't even think of that good catch. I will take more pics and post. I work tomorrow but should be posted on Wednesday. Still a little sketchy about the H case but my engine builder rocks so I will be patient for the verdict Got the NOS exhaust all painted will post pics at same time. Thanks again for the advice, Peter | |

| Is the T3 case dual relief? I wouldn't build a single relief case for your application, especially if you use a doghouse cooler. The H case should have 6mm oil cooler studs, you'll need 8mm for the doghouse cooler. Make sure you use a bigger oil pump than the stock 19mm on the H case. If you use a stock flat faced cam that will mean an aftermarket pump (easy to find and inexpensive). I have a stock 1600SP in my bus also. Good Luck! | |

| I'm also running a 1600 single port engine (with doghouse cooler set-up) and a 30 PICT carb (rebushed and re-built) in my '67 Campmobile and I'm very happy with it. Well-built, this is a great motor for a Bus. I had removed a 1600 Dual port with Doghouse cooler and Weber 34 ICT dual carbs. It was good, but I like the torque, and smoothness of the 1600 SP better. Bill Thanks for any help! | |

I don't know, I had a 1600DP and I liked it better on the highway, it seems like the SP starves for power up top......... Currently building a 1904DP for mine, partly because Rancho sold me too tall of a gear in my new tranny.

Yes, a 3.88 is too tall for a 1600. It will make your 1600 feel tired or a lack of power in 4th gear; most people feel it is not a good combination. I regretted it myself when I did it and wish I'd gone for a 4.12. If you are geared for a 1500/1600, a 1600 is a good reliable motor. If given the option, I prefer the later case with later alloy and dual relief and yada yada yada, but have also driven on H cases and been fine. I put all the tin and thermostat stuff on there, and don't seem to have overheating issues, even when loading the bus with a (literal) ton of stuff and driving to California in 90F+ weather. An early case with early cooler works, it just is more vulnerable to overheating issues. So you might ought to take it easy on hot days if you go that route. TIN:

| neither case appears to be dual oil-relief. I would not bother with these, have patience and find yourself a decent later factory doghouse dual-relief case. _________________ drive your split. | |

| You might want to consider going to 1641 cc P&Cs and or 74mm forged CW crankshaft. For that extra bit of power, with not going over board in cost in parts or machining, or stressing out the engine case. _________________ In Stereo, Where Available! | |

| Thank you all for the great suggestions and Helping me with my build. Sled I have been contemplating on a later dual relief case as well but had these so thought I would go with one. I am going to see a dual relief tomorrow and see its condition if looks good may just pic up and go dual relief. Will check code also before just purchasing, it was in a running car but has been stripped of some parts, fan shroud alternator,etc. Bill is your case a single or dual relief and what distributor did you use? Thanks in advance. Clara Thanks for the parts pics its perfect refresher for the parts I will need blasted and powder coated. Bruce you are right sir they brought the studs up to my attention yesterday as well I am looking into dual relief now and definitely on the bigger oil pump!! Eric and Barb have thought about it but still haven't decided but suggestion is definitely appreciated. I appreciate you all for the suggestions please keep them coming. | |

| engine number on your type 3 case is here. If it's not drilled for the oil pressure sender, you can run a type 3 cooler in your doghouse, that's where the oil pressure sender goes on a type 3 (you can see that in the pic too, except it lays flat on a type 3)
