out of intrest im wondering what combo you guys are running?
there seems to be 2 main chev combos but im wondering if anyone is running the 307 block with a 400 crank? that comes in at 357ci at 30 over?
the norm is the stock 350 stroke 30 over bore (which is what mine is) and the 400 block with 307 or 327 crank 357ci at 30 over.
i have looked into the holden options as well and for under 12k you could land a holden 355 ready to bolt in for around 12k and that motor would be aprox TORQUE: 535 ftlbs @ 5350 RPM- Carburetted and the HORSEPOWER: 558 @ 6700 RPM-Carburetted with a compression ratio of 10.5 to 1. but having spoken to the guys that build them an increase to 12.5 to 1 and a more aggresive cam would bring the hp to a smidge under 600hp and the torque to around 570ftlbs (of note the 396 version (thats 3.8 inch stroke) makes 710hp with a comp ratio of 10.9 to 1 which would be a dam good modified motor) Good old LP was telling my uncle a few years ago that the holden motor was a better engine than the chev apart from the head gasket issues.
what is a ford producing as i doubt that it would be as much as the holden due to the valve angle of the holden engine (6 degrees). but the problem with the holden is keeping the cranks in one peice and the head gaskets to not blow. (this depends on which block you use and if you spend a little more on the crank.
any other ideas out there?

These saloon engine threads are getting tediously boring.......... Just do something different , turn up and show em how its done.....or not.
The great innovators in motorsport didnt ask the world first, just turned up with something no-one was expecting. Sometimes it worked, sometimes it didnt , sometimes it was banned !!!

400 block with 307 or 327 crank 357ci at 30 over. That's a 353 by my calculations? Never heard of anyone running a 307 block - would be an expensive set of custom pistons to get the bore/pin height required... and why would you bother as its not going to be an awesome engine... And 307 blocks must be like hens teeth! |

And 307 blocks must be like hens teeth! they are common 3.875 inch bore same as the 283 "Common" is a relative term - 283's are far from common as well! Common is 4" or 4 1/8" as that's what most Chev engines use, so by supply and demand the best priced gear is going to be in those common sizes, anything else is odd ball = probably expensive. |

hey scott my car is in the garage with its motor on its way to the engine builder to freshen it and also you should check out the entrys on the queens birthday list for sunset speedway. from what i hear there may be a problem with inline 6s in the mustang body your running. worth looking into and isnt Ian shingleton running 11w in saloons?? well i will be one of the first to bite my tongue if your car makes it to the track ;D and yes there could be an engine /body problem but i await the remits final call. and yes my number was stolen you should get your facts write first before you accuse me of STEALING a number. maybe if you had rang the speedway-club like i had done scotty in January this year and asked for a number 11 and given the okay by Michelle as there was no interest or it penciled to any person how can you say it was stolen from you. Hopefully this is put to sleep NOW. Ian Shingleton |

I would of thought with saloon car 350's if you run what you brung you have a good chance of getting banned. So its just a matter of holding the spanner in one hand or the rule book in the other. What are the expert opinions on the chevy cam belt drives for saloon or are they considered illegal ?
