Dart motor in a 85 442

[olds307 and 403]

The Dart motor and the LS make sense. The LS has much more potential than the sbc. Unless a sbc has efi, they don't get better mileage then the Olds V8, maybe worse. We now have a decent aluminum head around the $1000 mark for Olds. I wish the would offer a 65-70cc chamber vs the 77cc. LS guys with carbs are kicking butt in the mileage department too. Personally I would put ina new Hemi in with 5 spd auto or 6spd manual before any of them .

If you are talking about the Pro Comp or Pro Star heads for old's then i got some bad news for you. They are made in China and the quality is very bad. The only way to possibly use these is buy them bare and have a local shop work them for you. I have heard finishing cost as much as just buying a good set to begin with like Wenzlers or Edelbrocks. And as a bonus when you open your hood you don't have to tell people half your engine is made in China.

with that brought up I would say it is far worse to have a bunch of Chinese parts on your car than not having a olds. also brought up is the availability of efi for chevy. there was never a olds efi setup stock and a aftermerket setup is not for people that do mot have thousands to dump into a efi setup. I am pretty sure I am putting tpi in my 442 but hesitant just because I am taking away the 4 barrel of the 442 but I also intend to drive long distance to shows and gatherings so the efi makes sense. I would go ls over anything if.I was starting from scratch. I already had my sbc that I built years ago so it was a existing engine from another project. otherwise ls. I build marine engines to, 90% of marine engines are chevy based and it is that way for a reason. if anyone knows about marine motors they know they are built to have the snot beat out of them. marine motors have to be able to run high rpm.under load for long periods of time. I run at 5000 rpm for up to a half hour straight sometimes. thers are guys that run much higher rpm for extended periods on poker runs. not 10-15 second passes on a track... just something to think about when people start bashing chevys. ls motors are now making their way into high performance boating too

FYI..... Oldsmobile put multiport EFI on 350's in the mid 70's with an analog controller. I have 1 with an aluminum intake and another made out of cast iron. Cadillac used them in the Seville. Chevy put TBI Oldsmobile V8's in some of there late model wagons.

Actually Olds engine builders have found pretty good quality in the Procomp Olds heads castings. Benard Mondello stopped selling the Procomp preassembled version. I see he is selling them again, either he is going through them or they took his advice. Most of the cheap sbc heads will be cast in China and finished in the USA, maybe. The efi sbc makes way more sense, since there is decent factory multi point injection. I can see why die hard GM guys stick to the G bodies, the new stuff is so ugly. I don't mind driving a Dodge and the new Mustang wouldn't my feelings either. I go Olds because they were so much more reliable than anything we had with a sbc, years back. Remember we had the late 70's sbc's. What blue smoke puffing, cam burning turds they were. Best one made 280,000 km before boom. Our 75 Cutlass went a lot longer and the last were very hard miles. Sold it for scrap with a rod knock and frozen caliper. Bet it stayed on the road another 5 years. 81 Delta 88 with the non CCC Canadian 307, over 400,000 out of it.

Regalman,

Are you really set on the TPI for your sbc? Reason I ask is the TPI was really made for the intake flow of the 305, not a 350. Even with porting / extrude-honing the stock runners really aren't up to the task of a healthy 350. Even the aftermarket siamese runners aren't much better. Wouldn't a ramjet-style intake be better?

Anubis,
You jogged my memory about the 350 Olds-powered Sevilles but didn't know they were actual multi-point units. I thought it was more of a TBI unit, similar to the units that came out on the abysmal Corvette / F-body cross-fire units.

that olds efi stuff is intersting but I dont think its ideal for.anything in todays world. the tpi I am putting on mine is because I have all of it sitting at my house already and I have allot of.the performance parts for it. computer n harness ready also. later on I want a holley stealth ram but at this point I just want to use what I have laying around. I do not intend to race the car, I just want a good.solid running dependable engine. I was going to hold off tpi but I have to control the transmission and electric fans and.the tpi is all ready for that. ideally I want a ls motor but my budget says not yet. I have 7 cars, a performance boat, house and 2 kids sucking money out of me l

Calling it a multiport system may be a bit of a stretch. The Seville intake does have individual injectors located above each intake valve just like modern intakes but I believe it was batch fire. Just like you eluded to regarding the TPI systems, the Seville throttle body does not flow well for performance applications but the intake can be machined / opened up to work with larger throttle bodies.

Regalman, understand using what you already have then upgrading later - smart move and more cost-effective for sure. Same boat here, with other toys then house and kids priorities shift (sometimes I swear I hear a vacuum sound whenever I reach for the wallet). But you're one of the rare lucky ones to still hold onto the toys. I'm glad you don't live close to me or I would have to check out your Calais 8) .

Anubis, thanks for the clarification on the Seville set-up. Again, don't have much knowledge on them so it is interesting they had individual injectors at each port. Yeah, with electronics being what they were pretty sure it was batch-fire but still...interesting
