you think its cheaper to swap a mod motor into a car?

so you go from a pushrod motor that can take 500-550 reliably before the block could go to a mod motor that has rod issues at 450... now i highly doubt someone would get a termi motor cheap and even if they did there is a lot more things that have to be changed to make it work correctly / reliably

Apparently you haven't heard much about me. Either way, I love both designs, and both have there advantages. I won't be doing either, can't afford it right now. Termi motor would be up my alley but I'm not worried about it right now.
Your probably right, I havent heard much about you. what gets me about mod motors is the $1k required for a set of cams. I wanna do a termi motor too, but have neither the $$ or the space to do the swap. cuz Termi motor + turbo= stupid fast car, no internal mods needed. Plus, I have found entire drivetrains for about $10K, where it would cost me that to build just a pushrod longblock that would handle the same power, after machine work, heads and quality components, like a Boss block.
I get parts free, or cheap, dirt cheap, many many many times over. Its all about who you know.
You don't need a set of cams in a DOHC motor. In reality the stock cams will support alot of power. There are other things amongst others that are much much much more needed. Simple fuel, and air upgrades will push the car to insanely fast. You don't even need to touch the heads.

Exactly why I said that I wouldnt touch the internals of the engine. I probably woudn't even pop a valve cover. I was planning on a huge fuel system, a big ass turbo, and using the stock heat exchanger. Having a 6 speed would be nice too!!
That is cool you get parts for dirt cheap. It is all about who you know, for sure!!!

By all means don't take it for an ignorant hate speech. I just find it a little hard to build a motor as unreliable as these are in upper power ranges, purely because of the block. If I was made of money, I would have a dart block or boss block, and would have absolutely nothing to talk about, but I'm not. I don't have that kind of money.

difference being a pushrod motor doesn't need rpm to make power
modo said:
RPM is related to camshaft, and with the right gear it doesn't matter. And last time I checked RPM wasn't a bad thing. Pushrods are a work horse, they just are, they will rip a stump out of the ground. But with VCT's on 3v's and the newer hurricane motors, I don't see "Torque" being a viable argument. Large CI motors, and vct's will change all of that.

my pushrod has seen 8000 rpm more then once, doesn't need it though as it is making 500+ rwhp at 3500 rpm. dont need stinking variable valve timing

But you need that block to do 8000rpm :tongue3:
not necessarily true but i agree over a certain power i wouldn't rev past 6200 on a stock block. motor balance plays a large factor into rpm
