Previously went on a talk about a 250 shot of Nitrous in a slant. I unfourtantly can't get forged pistons on time and saw the replies, i want to go alcohol on the slant. But the thing is it Will be a stock bottom end. Rebuilt with 10:1 compression. And a performance cam. Below are the specs. Also i am not trying to push the slant to extremes I merely trying to see avenues to go down to see where cheap power can be made. BTW this will be a 100% alcohol no mix. With the potential to mix in 20% nitromethane. Also this is for a drag race event in Arizona.

-Forged crank
-Cast piston that are newer if that makes a difference (silvolite)
-block bored .20
-head milled to get 10:1 compression
-head ported
-1.7 intake and 1.44 exhaust valves
-backcut on valves
-comp cams .440/.440 lift with 264/264 duration and 110 lsa (matching valve springs)
-i will be running it to 5k Rpms
-DUI distrubitor
-Holley 2 barrel 500cfm alcohol carb
-Zoomie headers
-Aussie speed intake
Basic maintenance isnt what I'm asking for cons. The real question will it hold up to 100% alcohol and mabye just mabye mixed with nitro
The science behind alcohol is it has a cooling property to it. This is the main reason I am trying to use it. Cast alluminum pistons melt with higher performance, also crack but I would say it would be more likely to melt due to the longer skirt on the slant pistons reinforcing it and a decent amount of ring to top of piston thickness. Now you can call me a moron for even thinking of an idea like this lol. But I wanna talk it out and see pros and cons. It will increase cylinder pressure and imagine the tuner myself is the best there is so we can take that variable out. What do the experts think? Horsepower wise we can plan on running on gas around 200hp. With methanol it probally will only reach 250-280hp i am not trying to go over 300hp experimenting with this slant and will probally blow it up but what's science without a big bang.

I know little to nothing about Nitro, but I know a little about 275 HP on gas. Alcohol should not be any different than gas as far as the bottom end is concerned. It should run cooler and allow higher compression.

You will not see 280HP without a good cylinder head, and a bigger camshaft. I would bump the compression a bit more and and figure you will be leaving a lot on the table with only turning 5000 rpm. Plenty of slants have gone down the drag strip at 5500-6000 rpm with a stock bottom end. I also would go straight to .060 overbore to be able to unshroud the valves a bit in the cylinder. Not sure what you are talking about with melting the pistons?? Maybe your talking about with Nitro?? Get the fuel mixture right and you should be fine. There is likely zero cost difference between boring .020 or .060.

Good luck.

You are right methanol equals to 130 octane fuel. The only reason I am not going higher compression is because if I do not blow it up. I still wanna run it on the street with pump gas and octane booster. If I have to. The nitro is the power adder, methanol will add some horsepower if compression is proper. I wanted to go .60 but the machinest said to wait. Because I will be ordering forged pistons and are only available in .25 and .45. I want to make sure It won't blow up first crank

What do you want to run in the 1/4 or 1/8 mile? what vehicle?
I can't help with alcohol, but what alcohol? Methanol, Ethanol, E85?
I know of one racer that ran N2O and alcohol. He ran race gas in the nitrous system, and the alcohol in the main system. But I can't remember if he was carbed, or injected.

You are looking at major problems. Gasoline, and methanol will require totally different fuel systems.

Then why are you getting off on a tangent. My 66 Barracuda with a 170 slant was a very low dollar build. Stock rotating assy (crank, rods pistons) Mild cam, milled head, homemade intake, made from a stock 1 bbl intake, with a 500 holly 2 bbl carb and fogger nozzels. Clifford headers. Stock electronic distributer with the advance locked out, and a HEI module, and "E" coil. 904 trans with a 3,000rpm converter, 3.91 SG 8 3/4 rear, and 23x8x13 slicks. Car weighed 3250 and ran a best of 12.905 at 101.85 mph in the 1/4 mile (60 ft at 1.76). It made a little under 400 lb/ft torque at 2900 rpm, and close to 300 hp with a 225 shot of N2O. Yes, I did break parts once in a while, but it was a cheap fix, since the short block was totally stock.
In case you haven't seen it, here is an older video, when it was running 13.2's and 3's with about a 175 hp N2O shot. https://www.youtube.com/watch?v=se4n19Frn2A&t=1258s
