Bristol's Chrysler Engines

[Markus Berzborn]

If you want to know what Bristol can do to modify the Chrysler blocks, just have a look at the current fuel-injected models.
And if you need more power you have the option of various engine upgrades which are even expressly mentioned on the official website.
It's really no problem to get significantly more power out of these American V8 engines, and it is no secret either.
Aston Martin Works Services offer similar services. They will upgrade your old 5.3 litre AM V8 to 6.3 or even 7.0, if you pay for it.

Markus, I think we might be at cross purposes - I was talking about what happened 40-30 years ago.

I assume the current engines are just bought in from Chrysler in whatever state of tune is required.

I can't imagine.
Bristol offer upgrades and conversions for all kinds of older models.
This would mean they dismount the engine from your car, and then the engine is sent to Chrysler and back again?
This really does not sound very realistic to me.

Markus -

I don't think sending the engine to Chrysler is necessary or
feasible. They are relatively simple engines to rebuild or improve,
with many sources of replacement and performance parts (or entire
"crate" engines) from Mopar and others - all the HP you could want
for $7,000 - $9,000, complete, much less for a rebuild. Search the
web for "Mopar crate engines".

I met a Viper engine specialist here who moved back home to Bristol
about 15 months ago. Not sure where he's working now, but I'd bet he
could be turning out stunning engines as a sideline if there's a market.

This is precisely what I wanted to say.

But you did not get my quote correct. I wrote: I can't imagine. Period. And then: Bristol offer...

Oops, perhaps I should have looked at their web site before making some of my recent comments! The home page hasn't changed noticeably in years (true to form) and I didn't realise there was now that great long list of mods and upgrades that they offer.

I wasn't suggesting that they sent engines back to Chrysler. I was going to say that the "upgrades" probably mean changing to the current Blenheim engine and that they probably don't offer upgrades to old engines, BUT, looking at the list of options I see they now offer the following modifications;

High Efficiency Engine Conversion (Sanction 1)
High Output Engine Conversion (Sanction 2)
Competion Engine Conversion ( Sanction 3)
Enlarged Capacity Engines

It seems that Bristol have a new lease of life!

Having had my own 411 engine extensively modified I'd love to know what mods they offer. I wonder if they offer fuel injection of old engines and if so how they are doing it.

Kevin

PS. Someone should let them know that Competion isn't a real word

Forgive me interrupting, but would it be imprudent to suggest that one of
you ring Toby Silverton at the Kensington showroom and ask him about the
Chrysler engine modifications performed by Bristol cars Ltd? I have always
found him and his staff to be very friendly and helpful, in stark contrast
to the "old regime".

It's good to know things have changed. Last time I rang up the showroom the chap I spoke to wasn't very helpful at all, but then I was asking probing questions about the Brigand as I was thinking about buying one. He did take my details and said he would contact me if one came up. The following day my representative at a London auction was outbid by Bristol on a Brigand. Despite the fact they had just acquired a Brigand I never heard from the chap at Bristol but I suppose they might have already had a buyer lined up.

Last time I was actually in the showroom, with a few fellow BEEFers who had just had lunch in the West End, I don't think the Bristol staff showed any interest in us at all. But then it was probably obvious that we were just a bunch of "enthusiasts". Toby Silverton wasn't there, although I think he was with Bristol by then.

I feel it would be a bit disingenuous if I rang up now and started asking about the available engine mods, given that my own engine is already rebuilt. But if someone is actually intending to spend some money with them it would be interesting to hear what options are available, and at what cost, although I guess that would depend upon the condition of your original engine. In particular I would be interested in V8 "Sanctions 1&2" (sounds reminiscent of Aston Martin DB4 Zagato).

My personal view is that unless your own V8 engine is in very good condition, it would make more sense to replace it with a modern Chrysler engine. If I had my time again that's what I would do, rather than rebuild and modify an old one. The only thing we ended up using from mine was the block! (although it would have been a different story if I'd had an earlier 411 with a pre smog 383 engine).

Would you please expand on the last point you made about the 383 engines, I take it that if you owned one of these you would have considered rebuilding it rather that replacing it with a more modern unit. I have a 411 /S1 with the 383.
