More research is required, but with a 2" journal rod and an overbore you could get to 375 inches or so, get the piston weight down to about 500 grams with a custom, a 1.84" or 1.94" intake valve and the port could be right for the inches, put a torker on it and spin it to 6500 or 7000 rpm. It'd make a real 500 hp, and that would make people sit up and take notice of the Rambler!
Now that would be cool!!

I'd be interested in seeing what the bottom line would be on the 375 cu.in. engine would do. Is it going to outrun the heads ability to dump thru those exhaust ports? Headers? My plan is long and I hope to start in it by fall, haha. I have enough spare parts to easily build an engine while using my stock 37K mile Jeep Vigilante. I hate the idea of the Torker, simply because I have THREE 327 4bbl intakes |

I wonder if the air gap would be a better choice now because they are better on the street and the bottom of the air gap would be easier to separate from the manifold? And they look cool.
I think two small blow-thru turbos would cure a lot of ills with a new self learning throttle body EFI It would be interesting to develop a torque-arm rear suspension kit like available for 3rd gen camaros and I think late model mustangs. You would need a new trans crossmember to accept the front of the torque-arm. A truck arm set up would work too. You could keep the stock rear and most suspension and bolt in any trans you wanted.

But the bullet, ordered an air gap intake, gonna build some headers and put dual exhaust on it, electronic ignition and get a cam ground soon. No idea what specs for a cam though or how to goabout it to be honest.

The 327 responds to cams about the same as a 360 would -- or any other V-8, really. I'd start with calling a cam company, ask about regrinding, then when they ask what you want ask for recommendations. They will ask what kind of performance you want and go from there. You can also research cams for a 360 and use the specs for one that sounds like what you want.
For a street engine I'd forget big hp numbers -- they don't matter, just bragging rights. A 350 hp engine setup right can outperform a 500 hp engine on the street OR strip if the 500 hp car is setup to run well on the street. It's the entire package, not just the engine. Big hp numbers are developed at high rpm. Unless you're drag racing a lot concentrate on making power in the 2000-4000 rpm range. That will be a good street engine AND perform well on track outings. It would be a bit mild for all out drag racing, but it's hard to make a good street/strip car. There are those who drive 500 hp engines on the street that do well on the track and THEY SAY well on the street, but lopey cammed cars are a bit finicky on the street, and deliver poor gas mileage and low speed performance in general. Yes, they CAN be street driven, but with a lot more driver input than most are comfortable with. Some like it like that... My recommendation for a good street performance grind? Isky 256 Supercam. 0.450" lift, 256 degrees advertised duration (202 @ 0.050"). The lobe center is 112 degrees, but you're going to be limited to the original lobe center, or very close. Rpm range is 1500-4800, perfect for a good street performance engine. A bit hotter is their 262 Supercam -- 0.465" lift, 262 adv. duration, 108 lobe center, 2000-5500 rpm. I prefer something that starts making power before 2000 rpm, as that's a good cruising speed, especially if using an OD trans. 2000 rpm in OD at 70 mph is a good economical speed. Without OD you want to run in the 2300-2500 range at 70 or so, 55-60 around 1600-1800 rpm. With a cam that produces good power around 1800 you can run a couple hundred under and still get good gas mileage and not have much lag in acceleration or hill pulling. |
