Hey guys. I've asked questions on here in the past (many of them pretty silly now that I re read the posts) about building a y block but always for my 59 f100 project. Well now if thinking about building a y-block for my other truck,a 64 f250 factory 4x4 with custom flatbed. This truck has a 352 in it right now (swapped in by the previous owner) which runs good but I think it's pretty tired. So I decided I would try to build me up a engine for it this summer. My first thought was a rippin and roaring 390 but then I had the thought of a 6.9l diesel but ruled it out due to weight and cost. Then I thought about a 300 with a 5 speed which is still in the runnings and then I thought well what if I build a good 292 and put this thing back to original. So I you tubed some y-blocks to remind myself how good these darn things sound so maybe I could justify the loss in power. Well I just can't make a decision so I'm asking opinions from those running y-blocks in your big heavy trucks regarding how happy you are with the power. Seems like with the correct parts and some knowledge I could build a motor close to 300 horse and hopefully around 350 ft-lbs. I'm thinking this would likely be a good bit more powerful than my current engine but I don't really know what my current engine is providing (a 65ish car engine with who knows how many miles or hours on it). The y-block is would likely be slightly more expensive but this truck is my daily driver that I'm never getting rid of so I'm looking at it as an investment. So what do you guys think is the 100 ft-lbs worth giving up for the pure coolness and clattery awesome sound of the 292.
