Always nice to toss the tennis balls in the intake tubes at the car show after you pull up.

You know they still make hilborn even got a street efi setup.

Hilborn Fuel Injectors

Also love the tunnel rams personally i would probably be using two 1050s race demons but i am a little stupid with my own cars. I usally run stupid big cams as well.
Love gassers, love vintage hard to drive brutal.....drove in this when I was about 13yrs old, holding onto the cage, blown BBC, balls out through first and second gears....I nearly pssd myself....and been in love ever since....this very car was a huge influence on me....as was the same guys Vega with a muncie and a 355....complete with ansen sprints and 70's ribbon paint lol....

3700 lbs and 488!! Not very street friendly. Good Luck. The only place you will not pass is a gas station.

60 mph comes at 3150 RPM,would be tolerable for a short drive. I drove with 5.13s and 28 tall tire until I bought a trailer.

I'm about 35k on the highway till I get into town, then I'm light to light everywhere...but I have no issue cruising at 90kph ....I had 411's and 28" previously and drove that 800k round trip to a show a few summers ago....was all good, except in the rain, sitting right at 3000rpm and small 235 tires made any dip or blip of the throttle a little sketchy

You will find that even thou your tunnel ramed, cammed up 350 is quite happy crusing at a fair good clip, that is not nessessarily a gas hog. Especially if /when you tune the carbs and spark advance curve correctly.

You will be suprised at how good it cruises. Cammed motors want to stay in their natural best rpm range to be efficient.

And if you dummy down the gear ratio althou it runs at a lower engine rpm, it does not pick up efficiency.
Neither in terms of fuel mileage or performance. Especially of it has a fair big camshaft in it.

Most people never realize the power a tunnel rammed car will make.
Tend to dummy down the combo too much.

This engine/ car/tire combo is begging for some 5.57's. Now you're cookin' with gas.

Using a shorter tire (say a 28-29" slick or ET street) for track days would really help it with 4.86's.

having the choice of two different tire sizes allows you a lot of flexability. Like on my car I use a very short tire for N/A and
a 2" taller tire for nitrous.

I must take a step back and admit something:

My head is usually in the "race" world. In the "street" world, pretty much anything goes.
People can do whatever they want to with a "street rod".

I really shouldn't give race advice to street people.
You do what you want, and be happy.
Like you said, it doesn't matter what I think. And you are right.

Having said that, if you decide to race it.... and you get whipped all the time... then come see me.
I might have some advice for ya.
( And so would 100 other people who hang out on this forum. )

Funny story that happened today:
This guy who works at one of our local machine shops calls me on the phone today. He is looking for some tires. A year ago, he was working on a project mid-80's tubbed Camaro. He finally got it running. I didn't have any tires for him, but I did have a set of rear-end gears. So he comes over in the Camaro project car to pick up the gear set. And guess what.
Yup... he was running a tunnel ram.
Talk about a crazy combination: 468 bbc, hydraulic cam, factory oval-port heads, 9:1 compression, tunnel ram with a pair of Edelbrock 600cfm carbs, headers, TH350 tranny with a 5,000 stall converter, 9" rear with ladders - 2.90:1 highway gears - and a pair of giant sprint car Hoosiers on some old-school Centerline solids.
I asked him, "you got a tranny temp gauge on this thing?"
He said no, but he had a big tranny cooler up front. ( good thing! )
So he takes me for a ride.
Funny thing is, he is getting away with this for a couple of reasons:
1. The car is fairly light.
2. That 5k stall converter allows the engine to rev up high enough to get that highway-geared rear-end rolling, and that tunnel-ram breathing.
3. The BBC makes enough torque to pull those gears.

I didn't say anything, but I was thinking about all kinds of advice for this guy.
He was in a hurry so I didn't get a picture of it, but next time I will.
I'll post a pic or two.

cool. Those summit pistons should be UEM/ Silvolite pistons. (KB pistons).
pay attention to the ring end gap recomendations for high perf applications based on heat volume load.
You must make the piston ring end gaps bigger. by about 40%.

EG: stock cast 350 piston ring end gap .016" Make it at least..024".
Failure to do this will pretty much guarantee piston failure when the rings butt.
(broken ring land)

The gaps in the running engine are normal, when its running. Al lot of people don't under stand this
and think the larger than typical gaps for these will create blowby and ignore the instructions, then blame the pistons
when things go bad.

This is what Weiand has to say about their tunnel ram intakes:

"For maximum performance in normally aspirated competition applications, Weiand Hi-Ram Tunnel Ram intake manifolds are the manifold of choice. They're designed primarily for drag racing, truck/tractor pulls, and performance marine applications where high rpm is required but bottom-end torque isn't. With their patented D-shaped port runners and large plenum chamber, they provide optimum thrust of the air/fuel mixture to the intake ports. They mount either single or dual square-mount carbs and, depending on the application, have power bands that run from 2,500 rpm to as high as 9,000 rpm. Separate tops and runners are available for some manifolds."

Do you have a dial caliper on hand there?
want you to measure the compression height on those.
Tell me the pin hole diameter and the distance from the pin hole to the piston top
using the dial caliper.

CH='s measured distance from pin hole edge to the piston top + (half of the pin hole diameter)
