I know a lot of people will say the 4v but cost to build a 4v "DAMN". Just was thinking. Why is the 4v so much better than a 2v? I understand the heads flow way better but is it worth it ? Hell I love the way a mod motor sounds with a set of cams. Just I don't see spending 1300 on a set of cams. Little expensive.

Cams are a waste of time.
Pick up a Mach long block, throw some rods and Forged pistons.
Degree the cams if you can. They say the 96-98 cobra cams are the best if you want a cheap upgrade.

Screw the mach block. Get a teksid...buy one from me lol, I have 3 complete engines in the garage.
Don't try and be cool by staying N/A...4.6ls are worthless turds in that form. Build up a strong engine, and throw some boost on that hoe
Boost on the 4v is great.Originally posted by Buzzo

why go with 4.6 when you can get 5.4 with 4v heads you just need to build?

4V is best, but you aren't going to make much NA power with a 4.6L. The 4V sounds better than the 2V IMO and I like the powerband on the 4V much better.Comment

Yeah I think they sound damn good. I was talking to a buddy he said there is no point in going with a 4v. Way to much money. But to build a "hot" 2v is not cheap either. I picked up a wrecked 01 cobra to do my swap.
I would like to pick up some cobra rods and pistons. Or just buy some from mmr. For the future. I know I'm going to want to boost the car. Just don't know what to do turbo,s/c? But time will tell. I know in the future I would like to get the heads ported and polished.
I think I'm going to get some of those 98 cams. Everyone says its better when degreed. But I also heard that that the 01 cams are not the worste cam either .Comment

You say that the heads flow better is that it? The motor is a fancy air pump the more air in and out the more power there is to be had. And if you boost a B Headded 4V you can make gobs of power with out even thinking about spending 1000-$1500 on cams/springs & tools to do the job. Not to mention valve seals and misc stuff it would require.
A stock 4v at 305 hp is a way better platform for high reving hp and takes better to the minor bolt ons etc. Then a 2v would.

4.6 stock bore and stroke is a perfect platform for boosted apps. And he motor is as close to square as you can get a 3.55x3.54. I wouldn't go past a 4.6 stroked to a 5.0 it you wanted some more cubes.
The 5.4 is decent in 4v form aswell but as a 2v + Boost the motor runs out of steam and a 4v will keep pulling...Comment

4V. Start from scratch w/ a teksid block and go from there w/ all forged components. Dont use b heads, use the c heads. Its not that expensive to build. Then add a blower or turbo to it../ ____ _ _\.

What are we thinking?
Ls swap. It's cheaper, faster, stronger and sounds better.

It's cheaper if you go with an automatic, but that damned T-56 is what kills you. Faster, yeah. Stronger, yeah. Sounds better.... No.Originally posted by 91CoupeMike View PostComment
