Building a V8 non-Tiger Alpine

Thunderbolt

I own a 1967 Alpine. I want to do a V8 conversion and it does not have to be a 289. What I want to do is emmunate some of the techniques used on the Tiger such as the firewall and steering. What or where is the best source of information and pictures for the firewall modifications? I am trying to avoid rehashing territory already battled thru.

Mods will be determined by the needs of the engine selected, along with the selection and location of ancillary parts (think steering pump, alternator, A/C pump, headers, starter, etc) used on the engine. The typical Alpine wears it swapped engine like a tight pair of jeans.

I have literally completed hundreds of transplants in other chassis', including fwd to rwd conversions and hundreds of crossbreed swaps. What is am looking for is pictures and information on what was done on the Tigers.

Tigers had a different firewall and different around the braces. Here is a picture with the pieces transplanted onto an Alpine. Brake master is where clutch was and pedals were different.

There used to be a lot more information here but much of it got lost years ago when the site crashed irretrievably. Still, searching here for "Alger" should give you a good start. As a general rule, the conversion requires access to a wrecked or rusted Tiger, unless you are a master fabricator, which sounds like the case here. British V8 has some information that would be worth looking at:http://www.britishv8.org/Search-Results.htm?cx=partner-pub-8168402389087911:7413808915&cof=FORID:10&ie=UTF-8&q=alpine&sa=Search&siteurl=www.britishv8.org/&ref=&ss=823j144807j6. And, you might find the photos and description of what was done to this car useful: https://bringatrailer.com/listing/1966-sunbeam-tiger-tribute/

One more thing you might want to consider is putting something other than a V8 in the car. If you haven't already, I suggest you spend some time reviewing some of the builds on this section of the forum. Some of them are pretty impressive and will out handle and out perform most Tigers. Of the three fastest Sunbeams I have ever ridden in, only one was a Tiger: Michael King/Alpine_64's Tiger with a 351 (I think) hot rodded V8. The others were Brian Holmes/tigretr's turbocharged 1725 (http://www.turbosunbeamalpine.com) and Jim Ellis/Jim E's 2.8 V6 S3, aka Vader. All three were neck-snapingly fast. There are lots of options for someone who knows what he is doing.

Not sure why you would want to replicate the stock tiger steering.. Its rubbish.. Poor geometry that leads to fulcrum pin failure, craxked towers, bad scrub, poor turning circle, understeer... The list goes on...

Even the MG midget rack conversion with MG steering arms and alpine tie rods is a step forward..

If you want an Alpine with a V8, buy a Tiger. It will be quicker, easier, probably cost less and will certainly be worth a lot more than a V8 conversion.

If you insist on doing a V-8 conversion, start with the knowledge that a short-deck (8.2") SBF engine with a toploader or T-5 transmission BARELY fits after removing the Alpine steering box and upper steering mechanism, fabricating engine mounts that "hang" from the original mounting locations for the steering box / steering relay lever assembly, moving the lower firewall back about 4", completely removing / replacing the transmission tunnel, modifying the inner fender panel reinforcement braces, modifying (or completely replacing) the front suspension crossmember to accommodate a front-steer R&P steering setup with terrible geometry and moving the brake and clutch master cylinders outboard by about 5". You will also need to cut holes in the front cruciform arms and notches in the rear cruciform arms to provide ground clearance for the exhaust pipes, remove the Alpine battery box and relocate the battery to the trunk and replace the Alpine rear axle with something that will stand up to "V8" torque (FWIW, a Ford 9" or equivalent will not fit without significant surgery to the rear floor / trunk panels).

A comprehensive side-by-side comparison of your S-V and a real Tiger would be a good way to start.

I have heard. Plan to use MG parts since I have them. I did a V8 MG a few year back.

Customer has to decide. I want to show him the challenges. It may end up as an LS or big 4. But the current request is to be similar to the Tiger. His wallet....my car is the starting point.

There have been a few nice LS conversions. More Pro Street with new front frame, firewall and fender wells.
