Well believe it or not it is absolutely true. Canadians are like Aussies, they don't care what people tell them they can't do they just do it.

You don't need all the racing crap to build a decent 4.3L on the street. The problem is people seem to think that they have to have small block power to be credible. This is a load of bunk, just build them for the street and drive them, there is nothing wrong with a 200HP V6 of any brand. There are a lot of 4.3L v6's on the street in all types of street rods that people think are small blocks. I have seen a lot of them at different shows. They are finally becoming common place. I don't know what the problem is with 4.3 nay sayers their just a version of the small block.

Look I don't care about Roddin' politics. I just want to build rods and customs with what ever I feel I want and have to use. Isn't that how it all started, use what ever you have at hand and for the budget you have?

You can find his Thames in that Blackies Fresno Custom Car show and at the Yellowstone cruise site if you want proof.

Dear Sir.I question the 500hp rating.Not the use of a 4.3 or the car,which btw is a very nice car,or him driving it to shows.I does get irritating to read everyone has 500 hp cars and knowing better.The split journal crankshaft I have good reason to doubt it would hold up under that kind of strain or would hold up for very long anyways.From what you are saying,his is holding up,so again 500hp....well I doubt it.I could understand you comments if I haven't gone down "that" road to build-up a Childress Bush grand national 4.3 that I bought at the Indy drag auction yrs ago and for good reasons spent the big money to get around the 4.3's design flaws.So I am setting here from a been there-done that backround and fully understanding the stock 4.3's.

Now is his engine a very stout 4.3??.Well I trust what you are saying and I would guess it is.You know full well what has been apart of hot rodding too is cars that are all show and no go,no show and all go,and any combination of the two.Here in Roch,NY-the Street Rodders club have members that readily admit they build a nice looking street cruiser.Nothing wrong with that at all.

I am stepping off topic with this comment.Damm I am sick of street cars making claims to hp.Who the hell cares??.Don't drive normally in whose higher RPM ranges anyways.We all have fallen in love with HP and we all know fully well in street cars,torque is king.It is more of the same romance that comic books like Hot Rod promote.

I don't care, but someone did care enough to compose a lengthy treatise refuting the claim.

Well Gary I really appreciate your comments but what you believe is up to you.
As for calling me a liar that's another matter. I think an apology is in order.
Anyways what is your problem? If you don't like the post don't read it and move on.

They used a Rotary Blower not even a 4-71 and it is possible with stock style heads!

This is the last I will comment on this particular subject.
