331 with trick flow top end kit or stock 302 with the truck flow h/c/i kit

I have a pretty much stock 302 with 160 km on the motor just wondering do I take the leap to go to a 331 or 347. I was thinking about the trick flow h/c/I On my 302 or is it worth going for more cubic inches. Winter in Canada time to build hp for next summer

If you are going to build a stroker, do it with a 351 based motor. If you are going to do a buildup next spring, wait till then. There are only a few things needed to drop a 351 right in and it looks like you already have a cowl hood if your avatar is any indication so you should not have any clearance issues. Cost winds up being VERY minimally more with the 351 based stroker but your returns will be ridiculous. A mild one will make 500/500 to the wheels all day, get 15-18mpg highway and be perfectly streetable with a good custom ground cam from someone like FTI or Buddy Rawls.

You'll need a new tranny regardless. Astro can build a T-5 that can handle up to around 600/600 but that's it. And honestly after that I would be going automatic anyway.

Google Astro performance. They make huge gears for the T-5 which makes it good for around 600ft lbs. They are very pricey at $2100 for just the gear set and around $2800 for a fully rebuilt 26 spline input, 31 spline output trans but its rock solid and shifts amazing. Make it $3100 and you get a G-force case which takes care of any flexing in the stock case.

Some people might ask why pay that much for a T-5. Well:

-Lightest trans out there
-Easily the best shifting trans out there
-Direct bolt in for apps with a T-5
-.59 overdrive with the Astro gearset and the stock overdrive gear

I was even kicking around saving up for one for my modular but the T-45 shifts almost as well and is as strong as a TKO and under half the price to build doing it myself.
