Gen V 454 Questions from a FNG - UPDATED

Hello everybody!

I hope you all had a wonderful Independence Day

I have decided to start hunting drivetrain parts for my future '55 or '57 BBC Gasser clone from my youth.
I have just begun scrounging, but have already found what I think is a good deal:

Gen V 454 - std bore, 4 bolt mains, stock, complete less intake.

I am wanting to build a serious street/strip engine: high compression, solid lifters, etc.

Since I am old school, I am unfamiliar with the Gen V specifics. My questions are these:

1) is this a good foundation for the type of screamer that I am wanting to build?

2) will the Gen V cause more installation issues in a Tri5 than an earlier BBC?

3) any known weaknesses to the Gen V (I know that they came out with a Gen VI)?

4) can Gen IV parts (intake, heads, waterpump, etc) be used with a GenV

Thanks for your help guys!

Thanks Rich

After reviewing hours of previous posts, it seems that some say you can use Mark IV heads on a Mark V block with the proper head gasket, while others say no way.

Who here has actually used Mark IV heads on a Mark V?

Any issues?

Thanks!

I have the guys that say you can't read it somewhere.

The GV has a better oiling system, the G 4 heads, cam, intake, etc will interchange. The oil pan and timing cover will not. The G 4 crank will if you use a RMS adaptor for the 2 piece seal. Any questions PM me and I will bet you lined out.


I have raced BBC stuff for the past 20 years so I have a little experience.
