Are the twisted wedge heads worth the money? Or would I be better off with some fox lakes or ported PI? Fox lakes arnt much cheaper (if not more expensive than twisted wedge), also I thought I heard fox Lake has gone to ****? I'm shooting for 300-350 rwhp NA. Thinking forged rods, stock forged crank (maybe knife edged or lighted?), and aluminum pistons (not sure what ones yet) for the bottom end. The heads are a big question mark for me. I was thinking comp cams 102560s. Not even sure what model TW head to go with if I went that route. I would prefer something pre assembled. Obviously I don't know to much about heads lol. I don't mind sacrificing a little low end since I should have my 4.56s in in a few months. And for the intake a ported and polished 99 is probably the best way to go right?

I sent a set of pi heads to fox lake and the guy told me straight up I'd be better off with trickflows

That's what I was thinking they are just pricey. Like around 1200 bucks for the assembled ones depending on what size valves and Springs. Plus another 600-700 for cams. So 3k just In heads then idk probably 1000-1500 in bearings, Rods, and pistons. Then another 500 in Studs and bolts. So by the time everything is said and done and it's running I'll probably be in 6500 just in the engine. Dam maybe I shouldn't rebuild lol then 2k in a trans

Almost seems cheaper to build the bottom end, do a port job on the pi heads, get a decent cam and L swap it

I'm gonna do some research. I wonder if I can hit 325 rwhp on pi heads with out sending them to fox lake or spending a **** load on port work. I'm planning on doing something in the 9.5-10.8:1 Ranger for compression

If you have any aspirations of building a high hp NA engine and later maybe boosting it, you will be limited by CR and cam choice. High CR, an aggressive camshaft and cylinder porting to match the cam would be path for over 300... But good luck. I saw one guy on the corral forum who hit almost 400 on the dyno out of a 5.4 2v. He also was maxed the with largest heads and most aggressive cams he could


I would shoot for a moderate NA build that would be boost friendly later

That's what I was thinking to that's why I didn't want to go much over 10.8:1 for the CR. Maybe a medium high CR and low boost. I'm gonna talk to Thomas about going 4v too, probably won't do 4v but it's a possibility. I also plan on keeping this truck as my daily for a long time so I don't want to go crazy with it. I want to keep it on pump gas obviously, but not E85 since I have never seen it here. Stock we are at like maybe 200 rwhp and 250 rwtq, if I could hit 300 rwhp and 350 or 400 rwtq without twisted wedge heads or boost I'd be happy

Personally I'd go my route without going over the top like I did if I had to do it again. Heads, studs, cams etc and leave the door open for boost. I wouldn't even consider building a 2v if I didn't see boost in the future

What's the specs on your engine and power numbers? I mean I would love to have a coyote but dam buy the time I get the motor, the trans, the wiring harness, the tune, and fabricate all the other **** I might as well just buy a new truck. Way to expensive
