Firstly decide what you want to do with the car Secondly decide how much you want to spend Do the two equate? Power costs money, sure it is fun but if you are driving to car shows do you need a 600hp fire breathing monster in a 1200kg car? Would you be.happy trying to keep that in check on a damp d...

I think for headline BHP, carbs can be tuned to match injection figures. However, injection engines will work properly across all throttle / load combinations, and all temperatures etc. etc. I have come to the conclusion that there is no real need for carbs anymore (with the likes of MegaSquirt) un...

Decided on settling for a Rover V8 powered Dax Rush. Seems there's a few 3.5 or 3.9 engine cars about, which engine is best in terms of getting the most power from it? Or should I hold out and wait for something with greater capacity? I know next to nothing about these engines but from what I've see...

Hey!! I'm not hating. I'm all for sticking stupid power into small cars. But thats for drag racing fun. If I had one of these cars for road fun I would want it to handle so I would be sticking something like a Fiat 20 valve turbo lump in there. Forged pistons sport exhaust and a few other goodies w...

400hp in a Dax Rush would be way too much power to be of any use I think ! Whats the point of having power if you cant get it down due to the lack of weight over the rear axle and non slick tyres? Hi I was just plain ignoring that discussion. Really the best engine for a seven is a thoughtfully tun...

400hp in a Dax Rush would be way too much power to be of any use I think ! Whats the point of having power if you cant get it down due to the lack of weight over the rear axle and non slick tyres? With the right tyres and decent suspension it'll work out ok for me. I don't intend on using the car o...

I think the simplest answer to your question is that as the iron block chevy only put out a few BHP as per your original post and you will need to change parts to get the horsepower you want then it doesn't matter which of the gen1 iron engines you go for as it'll probably only be the block and sum...

Why do you want, specifically, an american engine, and, of those choices, specifically a 350 chevy, in a rush? If you were after a cobra rep, I could understand it more, but a rush is more caterham 7 style. You say you want around the 400 horses figure.... that's a lot for a rush. They weigh bugger...

Hi 4 bolt mains are 4 bolt main caps on the middle 3 main bearings. 200 runners. . 200 cc runners in the heads. basically 200cc to 210cc inlet runners and about 23 degrees of cam timing at .05" on a roller cam will give you a road drivable 400 to 420 BHP and a high rise duel plane inlet manifo...

Look for a 4 bolt bottom end, good aftermarket aluminium heads, you will probably need 200 plus runners for your goals, compression around 10-1 if its built properly and with the right cam 400 hp is doable, but you will need it to rev to get there. Have a look at the multitude of crate engines givi...

I think you'll need to be very very lucky to find a Rush with Chevy 350 of the exact spec your after... It wasn't a popular engine choice for the Rush I recon only a handful ever built. Tom. I'm simply after a car with a 350, not necessarily one with exactly 400 odd bhp. Just seeking the info on wh...

For a dax I would be looking for an Chevy aluminium block LS engine. They are light so won't harm the handling like the old iron block chevy will and they are also compact, not a lot bigger than a rover engine. Depending what you went for you could get your power goal from a stock crate engine. htt...

Soon to buy a used Dax Rush. Looking for a car that's powered with an American engine. I'm aware that one or two appear here and there in the classifieds with Chevrolet 350 c.i's. I have hardly any knowledge about these engines, although I'm aware there's been certain revisions since their introduct...

Good evening and welcome to the forum. The formula 400 sounds an unusual beast do you have more information, do you have pictures? best regards Mike Thank you Mike :) She went along time ago, I only owned her for a short period of time. Needed a fair amount of work to get her in the condition I wou...
