This is probably where you should start. I think this has been Howard's mantra from day one. Figure ot what transaxle you will be using, and many of your options are settled. Big block FE have been fitted into MkI replicas, with interesting results: 1966 CAV GT40 - 640 HP For Sale | GT40...

Gordon also has an awesome 351W displacing 355ci which is a detuned race engine. Output is 530 hp and 450 lb ft of torque. 7500 rpm shift point with a 7800 rpm rev limit. RPM limit can be raised, as can power. He also has/had a destroked 351W displacing about 317ci (IIRC), which revved over 10K...

Andy - we're not talking material, we're talking design. The Veyron, McLaren and Koenigsegg all have CF chassis that are made of compound molds which are glued together and baked, and are not made out of flat panels that are glued together and I assume baked. Jim's point was that the strength in...

It also has a twin vent nostril whereas 1075 had a single vent. I also believe 1075 doesn't have side mirrors. And I believe 1075 only has a filler cap on the RHS. And it is missing the lights for the door meatball ... Ian

And, while ERA bodies are fiberglass, the spiders have kevlar/CF. Ian

Hmmm, we have proof of a CF rear clip: http://www.gt40s.com/forum/gt40-build-logs/20463-southerngt-no8-12.html#post290192 About 28kg difference between CF rear clip and regular rear clip, or about 61 lbs. Ian

I've kind of always felt that way myself ... Ian

Here is an example of very nice looking and functional fabricated steel uprights specifically designed for a GT40 replica (CAV): http://www.gt40s.com/forum/gt40-tech-chassis-brakes-tires-wheels/34991-christmas-july.html Ian

Firstly, build it the way you want to. Secondly, there is no minimum HP/torque. It all depends on what you plan to do with it. Many feel that HP in the 350 - 400 range is more than sufficient on the track due to the 40s low weight. IIRC, even the Wyer Gulf cars only had 425 - 450HP, and they...

Michael, I would be very wary going that route. Moving VIN and ID tags from chassis to chassis can be very risky, and you risk losing the car. Also, at that point, you would have to meet 1974 smog requirements, which are going to be much stricter than 1965 and 1966. Basically, you are trading...

Michael, The speed at which SB100 certs "fly out the door" has drastically slowed down. I believe that even this year, there were numbers still available in June. ITG makes some nice inline air cleaners which may be smog legal, and K&N has some cleaners that install on pairs of throats so...

Michael, I am pretty sure that, assuming you have all of the necessary receipts from John (chassis construction, body molding and work, engine, transaxle and wheel purchase, etc.), you should have no problem registering this replica under SB100 since that is what it is - a replica. Ian

Similar to the Subaru SVX: http://mycarblog.org/wp-content/uploads/2010/09/SVX1.jpg Ian

This is probably the best and most effective route. Open the NACA ducts on the front clip and, assuming the proper ducting isn't already in place (RCR has the ducting in place I believe, and ERA has a full fresh air system) add it in to vent the air into the cabin. Then you can use the "toll...

Depending on how hard it is raining and how long the car is in it, unless special attention is paid to installing the door eyebrows and properly installing the weather stripping around the door, you can minimize water entry (I am not sure if you can eliminate it completely). The design of the...

The Gulf flares make the overall width 75 inches. Since the replica manufacturers offer both normal and Gulf versions, it makes more sense to use molds without the flares and add them in later than to use molds with the flares and remove them. However, if the concern is that you would have...

Also note the significant difference in dimensions between the new Ford GT and the original GT40. The GT40 is a very small car (a Porsche Boxster looks big when sitting next to a GT40). For example, look at this picture: http://www.gt-forty.com/GT-Forty/Body_files/original.jpg Ian

You might want to look at the 2005/6 Ford GT again. The side windows are two pieces - a triangle in front, and a rectangle main part. Also, compare the Ford GT with the GT40 and note the difference in the angles. The 2005/6 Ford GT has a smaller angle when compared to the door axis, making up...

Re: Factory built RF For Sale I read somewhere that Shelby played with crossram manifolds a little and produced more HP vs. regular Weber set ups (and even some 4bbl carb apps). I don't recall why they ditched using them though. The straighter shot into the intake manifold should improve...
