Max effort combo? Started collected bits...:)

We have a class over here called true street, car must be standard chassis....naturally aspirated, no tubs or engine bay mods of any kind, 3500 pound min weight.
The only car we can use has shocker towers similar to a 69 Mustang.... which cannot be cut.....


What power do you estimate we could make with the following;

Cast block
Wet sump, vac pump
Any Head, manifold, carbs
Any fuel



Cheers, George.

Not scared of maintenance but would rather not change valve springs every 3 runs....

Would like to know if 1300 is possible, & what components it would take to get it there.

Do you think the Thors maybe too big for an N/A Deal?

What about the Profilers, are they worth the extra cost compared to the C's?

Unmolested shock towers are gonna make a good set of headers for that thing a "special kind of fun".

So true!!! Not to mention the cost on HP.............

You do not want to change valve springs every 3 runs but, you're not scared of maintenance. .
So, how about refreshing the entire engine every 15 runs or so ...? You would be building somewhat of a street Pro Stock type engine IF you are looking to be THE fast guy..

Otherwise ... "Max Effort" has an entirely different definition than what I am familiar with.

That's why i'm asking, to see what it would take.......it's purely hypothetical at the moment.

Could be wrong but i wouldn't think a 1300 hp 650 inch motor would need a complete overhaul every 15 runs?

WHY WOULD YOU EVEN THINK ABOUT A WEDGE HEAD?

WHY?

Maybe a good reason why George is thinking wedge head, is because there is a lot of really good running big horsepower wedge headed engines out there,,,,with Thor,,, Pro-Filer,,, and C-D or E-460 heads on them.

Maybe another good reason is because he said, 69 Mustang with factory shock towers that were uncut. If my memory is correct, Kar Kraft had to cut and modify the factory shock towers to get the Boss engine in the engine bay of the Boss 429 cars.

and as far as Thor heads being to big, out of the box they might be, but by the time the head guy is done with them they will be right.

This motor your looking for is not an off the shelf bolt together build.

There is only 5 meetings per year, we'd probably only need to do 30 - 35 runs plus some testing.

It'll be a massive task just trying to fit a wedge head.

Absolutely Charlie, i don't mind spending money on good components.....if we'd have to sacrifice a little horsepower for a little less maintenance so be it.
I've seen you guys make 1200 with c-heads, what i'd like to know is if we spend the extra money on better heads & intake how substantial the gains would be?
Thanks.

Where does it say hes using a mustang?
No matter what headers will be a lot of work

George says it in his first post, second paragraph.

This is the body style i'm thinking of using guys.

he said "similar to a 69 mustang"......

XA falcon coupe nice car
you can fit a C headed engine into a xa with out to much problems..i have done it before i tube framed my xa.
a set of custom headers and a special made spark plug spanner and you are away....

come down to this side of the world and they are nearly as common as a mustang....

The darn steering wheel is on the wrong side.
