Post your 500ci street/strip combo's with ET

[wyrmrider]

We need to know the whole combination- which is an iterative processes
First have Hughes tell you what the final cc of the heads will be
then give us the pistons and deck clearance and calculate an accurate compression ratio
We will need to know the cam as a high torque cam will flash much different (lower stall reacquired) than a big high rpm cam (higher stall required)
cam selection for stock exhaust is different than with headers
and we need the gears you are going to use
a high stall converter will band aid but will not solve the common problem of overcamming

Who is we? Contact name and or number?

Any help in recommending a Torque Converter for this build would be appreciated. What stall speed would be a good street sleeper? Thx.

Based on what you posted, probably stock to 2500 rpm. I would use whatever you have, make an assessment, them make a better decision from it.

This car has impressed me since the first time i heard about it and being a factory L code car its just killer man. Runs so so hard!

Hi B-Bods,
We built a 511 440ci motor a while back and hope to run it in anger this year!
67 Gtx block with a 440 Source 4.250 kit, dish pistons, RPM Edelbrocks and manifold.
Crane-Golds, Crower .550 roller, TTI headers with a 950 carbie, (now in a stock full bodied C-Bod. over 4000lbs)
13.2 with pump gas and and no tinkering after a 200 mile run to the track.

Will be transferring the motor and trans into a 71 GTX next year. (bigger cam etc.)
Hope to run tens eventually, if the motor stays together lol...

What RPM are you guys shifting at and your redlines for the 500+ci?

I started at 6200. last time I had it out I was short shifting. Around 5800-6000, didn’t seem to bother the Et much at all.

67 GTX. This build is currently fluid. I'd like to say we are shooting for 500 ish HP and 9.5 Compression or higher.
Just sent my 915 heads off to Hughes Engines for porting and machining.
The plan is for a street sleeper to keep as close to looking stock as possible.
The additional plan to date is:
Block should go in next week for machining and sonic
505 Stroker Kit from Hughes
This time going with Hughes recommended Cam and Torque Converter
Holley Street Dominator Intake (hood clearance concerns)
Holley 850
Sticking with Exhaust Manifold (looked great when we pulled)
727 rebuild with shift kit
Gears 3:55
Still up in the air:
Ignition
Oil Pan
Radiator (leaning toward sending existing to GlenRay for stock look/I know it's pricey but man they do good work)

I stayed with 915 heads because of one year only and remains original. Plus I have read goods things on this forum. Oh and when my dad built his race motor for 71 Challenger in the late 80's he used 915 heads.
Thanks for this thread.

After researching the radiator that came out of this build it is an aftermarket. Has the original look but no markings. After reviewing similar radiators on this forum I think it is a US Radiator. It looks to be in very good shape. Don't know how old. Pictures below.
So would it be a gamble to go with it AS IS with this build? Car does have original fan and shroud. Both in good shape.

 

[wyrmrider]

looks like a good radiator 3 or 4 row?
brass cools better than aluminum
I run a 73 4 row New Yorker Radiator in my dakota (Imperial was a little too big)
1 max frontal area is more important than rows
you can always zig zag the coolamt flow
you can keep the tranny heat out of the radiator
also important is to plug up any holes in the core support
and a spoiler/ valance or ? uunder the core support or bumper really helps on Dart's I've used those from an S10
Full size Chrysler from a chevy or Ford PU or whatever factory one I can find

Mine not done yet got one more month but kinda standard build. 440 + 30 stock crank 440 source heads with matching intake and exhaust ports. 284 grinder 7 at pan 10 flat tops working on head gaskets heads are 84cc. Running 6pac on top won't know what it will until June just finishing it up. But this is a great thread keep them coming

Well we are making progress. See attached.
Will be adding a Holley 770 instead of 850.
Torque Converter will be a 3000 stall. It's down to either Hughes or PTC.
TTI headers.
Sticking with the factory look 3 core radiator.
Went with the 6 quart Mancini oil pan.

My question is do you think I will need a transmission cooler? It will be street driven and at times sitting in traffic.
Thanks.

Can pick up a b&m cooler fairly cheap $70-90 bucks so why not. Won’t hurt.

 

[wyrmrider]

Get the 1/2 in 1/2 out 100 plate and fin cooler approx. 1 foot x 1 foot
no tube and fin coolers
mine are Brogwarner Canada
or get one from a ford PU from Picka and pull
V10 fords have amazing coolers
stop and go is as hard on heat as towing especially if you have incrased stall

Here’s one from 10-12 or so years ago.....

68 Charger, all steel, full interior, wipers, etc...... about 3850lbs.
727, Dana w/4.10’s, 5200 stall.

4.500 x 4.15(528)in a megablock.
Eagle crank and rods, flat top ross pistons, 14:1cr.
Std port size B1-BS heads flowing around 320-325, 281/281-110 .690 lift roller cam, T&D rockers.
MP TR with 2 x 750dp carbs.
Dynoed 740-ish @6000rpm(heads too small for the cubes).

With cal-tracs and leafs it went 9.80’s.
With ladder bars it went 9.70’s.
Besides hooking better with the ladder bars, it was also a bit lighter.

A few years later the top end got swapped for some Indy 440-1 cnc345’s, the Indy TR, and Jesel 1.7 rockers.
It picked up about .45 ET(best was 9.26 iirc).

Absolutely get one. That converter will generate the most heat under two scenarios: when cruising under stall speed and when you’re going balls to the wall.

[polyjohn]

A very nice TOY there Duncan!

I guess the Victor intake and the 150 shot of NOS has given you a BIG hit in the 1320, coolio...

I thought the 67 Charger were much lighter than that?

 

[polyjohn]

Nice build there Craig!

I'm doing a 512ci build for my 71 GTX too.
As I have flat-tops I will use some 906's or 346's (as were stock in 1971).

Any porting pics from Hughes on the 915's?

Your engine looks very similar to my Mopar-mates 512ci in his 66 Polara. (avatar pic) He was going to run his 915's but went Eddy's instead...

Where ya been HT! Last seen June 2020. Hope Dan is okay.
