Ok stockers.. I dont want any lip I have a few engines at my shop that Im concidering useing in my 1960 F-100. This are all Marine engines..

1988 MerCruiser ( Chevy Block ) 383 HP spread bolt

1976 MerCruiser ( Chevy Block ) 502 HP 6 Wedge Bolt

1989 OMC ( Chevy Block ) 350 HP 4 bolt

1968 OMC ( Ford Block ) 289 HP 2 bolt

Thies are all true HP ratings .. I like to know how hard it was for all you who have changed there engines to Others than Ford for mounts and other things..

 

stay away from trans-dapt. i tried them, and the mounts bent.

i had a 289 in my 59, but have now opted for a 360 dodge. i did mine with a motor plate. and i like it alot. that motor doesn't move around anymore and it gives me a handy place to mount the relays for my electric fans and fuel pump.

as for tranny mounts, don't use the 3" drop, its not enough if you plan to haul anything with your truck. at least it wasn't for my application.

radiators and such aren't a problem as long as you don't mind doing a little fabrication. i drilled a couple of holes in my BB dodge radiator's brackets and was able to use it on the 59. the other option is custom rads that are relatively inexpensive from summit.

shifters aren't bad either. you can modify your existing 3 on tree shifter for the chevy or ford trannies. on the dodge i had to use an aftermarket shifter, which is another option for you.

with a motor plate and a 4.5" drop crossmember for the tranny any of those engines would be great. i'd update my brakes and make sure my steering components were all 100% b4 i dropped in a more powerful V8.
I did mine backwards the first time, and now that i have good brakes and steering i can't believe i ever drove it the other way.

sorry for the loooong post.

good luck,

sb

 

Aren't marine engines cammed really differently than auto engines? (I know some are cammed to run backwards for twin-prop boats, not talking about that)

I thought they had other internal changes too, that made them a poor choice for cars/trucks (as-is, anyway)?

 

marine Engines are all working engine.. Meaning that a car/truck engine is built lighter becouse thay can coast.. marine engine are built to work 100% of the time.. there great for a truck.. High torque and good RPMs.. The 502 for ex. is a true 502 HP at 2700RPM while the GM 502 is only 422HP @ 3000RPM.. marine engines are built to run under full power 100% of the time.. Most cars/truck only work 50% of the time.. the other 50% there coasting.. So marine engine are much strongers and wil out last any car/truck engine.. I have install a few in the past and thay have always worked great.. I have a 65 C10 with a MerCruiser 350 in it that does low 12 in the 1/4 mile and its a everyday driver...

 

502 hp @ 2700 rpm has gotta be a diesel, right?

 

nope.. Its a 593 CI Chevy Marine block.. Thats why I said true HP .. Marine engine are Hi HP Low RPMs Mild Torque Engines

 

If they are based on the car SBC (mounts, bellhousing, crank flange), the swap is a piece of cake.
