It also has a lot of "unique" sheet metal work, 4 bar rear suspension, coilover/strut front suspension, 6 point cage, custom dash, and a whole bunch of other mods. I build cars with certain parameters in mind and performance, styling, and handling goals planned out long in advance of the build ever starting. My ultimate goal is always to have all the components compliment each other and work together to achieve the goals I established in the planning stage. The 'maro is just a street drive, no big deal. The Ranchero would be most closely described as pro touring, with the objective being 250 mph at Bonneville. We used to have discussion here about building the car to a "theme"..... Doesn't happen much anymore I guess. About half the threads on here anymore are just a re-hash of which cam and heads to put in a sbc....... Nothing wrong with that, I guess. Just hate to see people limit themselves to just an engine, or just the paint, or just anything!!!!!! The entire car and all of it's pieces conveying the same theme and all designed and built to achieve a certain goal is way big fun!!!!!

CHEERS TO THAT!
you put it in better words than i could have. its really a great feeling to have done everything on your car yourself ( or almost if you dont have an engine boring machine or an englilsh wheel)

AAAwwww man, you're gonna make me blush...... I am working on a homebuilt English Wheel and Planishing Hammer----getting waaaaaaaaaay to old to use mallets and shot bags!!!!!!

Now you will have a ( 348ci SB ) or with a .030 over-bore a ( 352ci SB ) . COOL The TRW#s can be crossed .

CarCraft did it around 2000 2001 if you can find it on their site but i read in their magazine they used a 400 block 327 crank and used ford 4.9Liter (300 L6) connecting rods and got like 450hp out of it on pump gas

That sound like a wild set up . We have some of the 4.9 300 Ford engines at work . In 25 years I may have seen one throw a rod . We call them iron horses .

Dave I know what you mean . That's why My 1965 Mustang 289 K sits next to the Street strip Monte Carlo .

you wouldn't be able to use 5.7 rods unless you found custom 400 pistons with the proper pin height otherwise if you do what you say and get it together when you have it at TDC the #1 piston will be .500 thousands 1/2 inch below deck height so you would need a 6+ rod thats what sucks it would be nice if all chev pistons had the same pin height where you could swap crank and rods all day long to make whatever cid you want stroking or destroking

With the TRW#L2418F Piston the pin hight is set up to run the 5.700 rods . These are not 327 piston . They are made only for the 348 to 352 de-stroke build .

Hey Dave, you going to run twin engines and turbos to get that 250 mph ?? You start getting over that 150 mark, the hp need really starts to climb.

Hay Denny W I think that guy is running one of them FE 428s ?

Really? I didn't know that!!!!!!!

Here is a photo of the Piston That is needed for the De-stroke 400 build .

Yes, I'm quite aware that it does take power to go fast, and the amount of power required to go fast increases at a rate disproportionate to the speed. But it also takes a whole lot more then just power to get to 250. Lift, drag, downforce, lateral stability, spring ratings and shock valving, gear ratio's, traction (at B-Ville the lack of it), rate of acceleration, tire loading, and a whole host of other considerations come into it...... That's why I stated as an objective and not as some sort of silly___ claim.... We have about 3 years of (part time) research and 200+ man hours in the project so far. On paper it's close, in the real world it's at least 2 years and $70,000.00 away.

Anyway, it's all for real and sitting in the shop anytime any of you would care to stop by and take a look.....

Dave do you really think that Ranchero is a good Car/Truck to build for a high MPH Bonneville build . They may not even let you run some-thing like that . May-be it would be better as a street build . The Camaro would be the better car even with that 408 Ford engine for a Bonneville car . Do some more research !

Well, it's not quite stock anymore, pics in my gallery. We're doing it because it is unique and we want to. Nothing really unique about just another 'maro. And yes, they will let me run it. B-Ville has a class for everything from 100cc motorcycles to jet powered cars. Safety rules are the big issue and I'm quite certain it will meet all of that criteria

Whatever.....

Well, I thought it was a good reply... To further define, I'm not going through all that junk again. Bill doesn't need all the whining. I personally thought it was a reasonable thread for awhile. You are entitled to all your secrets. I have none, merely stated that anyone was welcome to stop by and take a look. Why you wanna get all defensive and start up and old argument again????? So, whatever was just my way of saying I don't really care to participate in another discussion about your engine.
