Gen V vs Gen VI

[BrendellaJet]

How do you tell them apart?

[IMPATIENT 1]

5 will have a spot for a dizzy on the intake, 6 uses a crank sensor near the starter area. if it has a hole in the block near the starter where a crank sensor might go its a 6.

both blocks use a regular distributor. im not sure exactly what is meant by IMPATIENT1s post, but i am not trying to contradict anyone.
for your block you definatly have the genVI since the pic shows a 6 bolt aluminum timing cover. the genV uses a 10 bolt timing cover similar to the mark4. now weather its a 454 or 502, you will have to either look up the casting numbers, or look at the side of the block between the freeze plugs. there you will see either a 7.4 or 8.1 in large 1 inch casted numbers.

[BrendellaJet]

Okay, It sounded like you might now be positive in your other post. This puts it to rest!

[victorfb]

yes, definatly a genVI. as for the block numbers, the 502 will have 8.2 not 8.1 on the side just above the starter and next to the freeze plug. sorry about the brain fart.

do they call the 8.1 a gen 6?, i know the 8.1's have a hole near the starter for a crank sensor.
i just went and looked at a gen 6 8.1 and yes they have the 6 bolt cover plus the hole i was talking about near the starter for a crank sensor since the gen 6's usually use individual coils per cylinder instead of a dizzy. both gen 5 and 6 have the dizzy holes, but the gen 6 has a dumby dizzy to drive the oil pump offa the cam gear.

no the 8.1 is totally differant animal. it was my mystake to post the 8.1 instead of 8.2 brain fart.
the genV and genVI are both based off the old mark4 block. the 8.1 is totally differant.

The gen 6 has a hole in the timing cover for a sensor.

ITS IN THE BELLHOUSING;) SEE THE LINK ABOVE;)

there's to many variations on bbc, we should all be runnin bbf's:D :D just external or internal to worry about with them,lol.

so the 8.2 looks like the basic mark4, well i learned something new today thanx:D i don't think i've even seen a 502 before on a stand, i need to pay more attention:( so it does come down to timing covers i guess for a quik indentity check. i can post pics of both style covers if you guys want.

[Infomaniac]

Timing cover is the dead giveaway.
1 piece rear seal and gen IV timing cover will be the Gen V block.

[kevnmcd]

block you definatly have the genVI since the pic shows a 6 bolt aluminum timing cover. the genV uses a 10 bolt timing cover similar to the mark4.
That is how I tell them apart, too.

[DMOORE]

GEN VI does not have a provision for a mechanical fuel pump.

[v-drive]

I wonder if jetdriver knows if it's a 502. Definately not the dne engine but it will still move that brendella.:D v-drive

:idea: :idea:

The Gen VI 502's do not have a provision for a fuel pump, but the gen VI 454's do.
the Gen V has a flat tappet cam, the Gen VI has a roller cam.
the Gen V has a 10 bolt timing cover, the Gen VI has a 6 bolt aluminum cover.
the Gen V has a double roller timing chain, the Gen VI has a single roller chain.
the Gen V has a standard cam, the Gen VI has a stepped nose cam with a thrust plate.
I'm sure that there are other differences too. The Gen V and Gen VI use the same style oil pan.
I know that the Gen VI crate motors use 3/8 rocker studs ( into the block the threads are 3/8 and then neck up to 7/16 ) in their large rectangle port head on the 454 and 502 HO motors. I don't know what the Gen V used on the studs

[Panic Button]

Gen V 502's do not have a fuel pump pad either.

[BrendellaJet]

Yeeehawww, its a 502!

[DMOORE]

The Gen VI 502's do not have a provision for a fuel pump, but the gen VI 454's do.
See, ya learn something new every day. I didn't know about the timing chains either. Thanks.

i had a strong feeling it was. hence all the mention of it in my posts. now you will need to remove a valve cover and get the casting numbers from the heads. that will help determin which 502 it is. most likely a 502HO. those came with rectangular port heads. i believe the casting numbers end with 088 but id have to check the files to be sure. there is a standard performance 502 that utilizes the smaller round port heads. same bottom end, differant cam and heads.
alot of potential in that engine, especially with more cam timing, and if you can afford it, a set of edelbrock heads with 110CC chambers then hog out the ports to match the rectangular victor jr intake. none the less, youve got a fully forged bottom end that can be a good strong runner for many many hours.
glad to hear the lucky find. :D

[victorfb]

Then there's the Gen 5 Bowtie block which as far as I know has the mech fuel pump provision....
yep, all bowtie blocks have the mechanical fuel pump. even the new ones. :D

[Daytona100]

yup.:D

[Infomaniac]

Wow my Gen V Bowtie does not have provisions for a mechanical fuel pump.
And.... I put in a stepped nose cam and thrust plate.

Well, as luck would have it, this motor is for sale. Ive already got a DNE 548 so the little 502 has got to go to make room for it. Ill pull a valve cover today and write down the cating # so i know what I have.

[Infomaniac]

Hmm you would be the one to know this, so I wonder whats up with that. Are you in a round about way saying they dont, or just yours?
Actually I have not seen a bunch of late model Bowtie stuff . Just mine.
I think I read somewhere else that Bowtie blocks had mechanical pump provisions. Sales/spec listing or something.
