ranchhopper Posted March 7, 2017 Share Posted March 7, 2017 I have a dilemma my superliner I'm restoring has a 300 plus engine which I did an in frame overhaul on last fall and has 0 miles on it what is a ball park figure as far as value? I have a line on a cat 3408 since this truck is going to be a parade truck and do shows the cat would be a much more impressive addition to the truck. I have also noticed the parts availability for the 3408 is much better and really not any more expensive and since the span of time I will own the truck it isn't going to be worked very hard. I'm not sure the 3408 will fit in between the straight frame rails of a Hayward built truck it is 998 cubic inches like a E9 so if the E9 fits the Hayward superliner the cat should also. Since this is totally funded by me for our veterans parades and to do shows the cost of the E9 wouldn't really be practical and a 866 really is harder to find parts for so thats my dilemma plus the fact I'm a glutton for punishment like I don't have enough to do on this truck to begin with. I was at the monthly meeting with the veterans group I'm affiliated with they were all excited about the engine transplant because the more wow factor the truck has the more our cause for the guys gets noticed and the fact I'm laid off for the winter doesn't make this any easier. This all hinges on what I'm able to sell the rebuilt 300 plus for to offset the cost of the bigger engine any suggestions would be helpful.

Popular Post TeamsterGrrrl Posted March 7, 2017 Popular Post Share Posted March 7, 2017 You really are trying to jump from the frying pan into the fire... If you want your truck finished for the parades next summer, keep the Mack motor. If you want to spend the next couple years and thousands of dollars fabbing up engine mounts, transmission mounts, air intakes, exhaust pipes, plumbing, etc. sucker for the Cat. To be honest, nobody will know the difference- Even if you can persuade the parades to let you run with the hood up blocking your visibility to show off that yellow engine, not even 1 in 100 knows the difference between a Mack and a Cat motor. If you're still worried about impressing that 1 in 100, paint the Mack engine yellow. If they ask any questions, act like an expert and tell them it was a product of a long forgotten 70s deal where Cat sold Mack engines, wouldn't be the first time Cat stooped to selling someone else's product as their own! 3 Quote Link to comment https://www.bigmacktrucks.com/topic/49038-will-this-engine-fit-my-truck/#findComment-363603 Share on other sites More sharing options...
Freightrain Posted March 7, 2017 Share Posted March 7, 2017 (edited) 300 Plus................hmmm, that'd make the ol B model fly!!!! I kinda understand the "V8" look, but how about just dolling up the 300? Some chrome and polish? If you are just looking for eye candy when opening the hood. Not that I wouldn't just love to take that 300 off your hands. (I need to find me a tip turbine) Edited March 7, 2017 by Freightrain Quote Larry 1959 B61 Liv'n Large......................

41chevy Posted March 7, 2017 Share Posted March 7, 2017 I'd take the money and time to do the Cat and invest in some dress up goodies and paint detailing on the 300+.

ranchhopper Posted March 7, 2017 Author Share Posted March 7, 2017 I guess I have always been a fan of V-8s but wedging a 3700 pound engine into that straight frame is a pretty big undertaking.

blackdog2 Posted March 7, 2017 Share Posted March 7, 2017 Whats the spec on the drive train will the v-8 stick out meaning drive shafts rears little frame trans 613-713 .

Timmyb Posted March 7, 2017 Share Posted March 7, 2017 I thought the 3408 was bigger than the e9. 18L vs 16.4L respectively. What degree is 3408, 60? 90? I think if your idling around you won't get as much out of the v8. Maybe straight pipes on the 300, and like what has been said, some dress up gear.

BGarofalo Posted March 8, 2017 Share Posted March 8, 2017 I think it's a cool project. They are a 60 degree vee so they do take up more real estate than the e9.

ranchhopper Posted March 8, 2017 Author Share Posted March 8, 2017 Just kicking around the idea depends on how ambitious I feel and how the cash situation goes.

theakerstwo Posted March 8, 2017 Share Posted March 8, 2017 As long as your dreaming then dream big.But when it comes to impressing the crowd thats a lot of money to get to be in the limelight for a evening. 2 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/49038-will-this-engine-fit-my-truck/#findComment-363703 Share on other sites More sharing options...
41chevy Posted March 8, 2017 Share Posted March 8, 2017 Abig yellow Cat is impressive BUT picture the normal uniformed oohing and aahing over a Patriot painted Red, White and Blue MACK engine. Generate more ego points than a kitty cat.

Hobert62 Posted March 8, 2017 Share Posted March 8, 2017 A 3408 fits in KW and Pete's with straight frames. But prob a lot more particle to keep the inline. unless you think that will fit in my b67.

57 bcr Posted March 8, 2017 Share Posted March 8, 2017 I loved my 300+ in my '79 R. The tip-turbine engines sounded great to me. A buddy of mine just went through his 3408.The gaskets were still available but totaled in the thousands. Give me that 6 banger any day. I understand the novelty of the big cat,just would not do it myself. But thats me,and what you do with your truck,is your deal.

jackb61sx Posted March 8, 2017 Share Posted March 8, 2017 You want to go with a cat and a different sound and less hassle put a 3406B in it, 425 hp and it came in the truck from the factory. It may not be the e9 but was the closest in power and reliability and lot better motor than a 3408 in longevity. I know mine runs right along with that in mine.
