Dennis the whole point of the 60 degree V6 is it's not a Buick or some other GM engine shoe horned in. It is the correct series of engine the car was designed for and better yet he has done huge hp naturally asperated . Yes it's harder to get these results but when you do there is nothing better. Way to go Rae. I like your style and detemination. For all you that prefer different engines and turbo or supercharging there is nothing wrong with that. To each his own and we all have the car that is the most fun of almost any car ever built. sleek

For me personally, I really like the "sound" of the V6/60. It's such a well-balanced motor when done properly... and this one sounds so fantastic when really wound out. It probably sounds better in person. Really, it kind of sounds a little bit like a Ferrari.

There is a video of a 3800SC series III engine where a full stack intercooler, improved exhaust and 3" pulley was added and the engine made 425 HP w/o any internal mods.

He has this Fiero in class racing. If he does an engine swap, it changes the class he's in. I think somewhere earlier in this thread (or his other build thread) he talked about the rules of his class, things about the block... maybe the heads? Anyway, that's why he's putting all that work into squeezing what he can from this platform.

Thank you Dennis! But I don't really have skills of fabrication. I see what Fieroguru, Ericjon, Will and Fierobsessed just to name a few have created with their own hands and I envy their skills. The only thing I'm good at is to disassemble stuff and see how I can make them better with unconventional thinking. Everything you've seen that "I've made" is not mine, I just tell my fabricator what I want and why I want it like that and let him do his thing and usually I get exactly what I asked. Sometimes I have to cut the intake in sections and bring it back to him and explain again why I want it this way, but sometimes what I get from him after I tell him what I want is way better than my original design! I grew up listening the the sound of the Formula One engines from the 80's and 90's and out of all of them two got my attention; the old Cosworth DFV from the 60's to 80's and the Lamborghini LE3512 in the 90's. Never liked how those turbo engines sounded muffled by the turbos. Anyways, I did extensive research on the DFV and the Lambo to see what I can learn from it and apply it to the tiny 60 degree V6. And that brings us to how I design the cam timing on my engines.
When I send the cam specs to my local grinder of what I want and what lobes to use for each side the intake and exhaust he just does it. The same cam company with the previous owner refused to do my cams, he was absolutely sure it would not work, the younger guy who bought him out has seen my work and he just do exactly what I want, they are SUPER weird for the veteran cam experts and the young YouTube Certified cam experts of today. It has taken me years to get the engine formula right but its paying off. I got it down to in a science, all calculated but ONLY for the 60* V6 pushrod engine.
And then there is the weight issue. The 60* V6 is much lighter compared to the newer V8's of today.

Mods are mods. That said, I generally don't compare boosted engines to N/A ones. With the mods we've done to the V6/60 we can spin it to 8000 rpm. I'd somewhat love to see him build a turbo version of his engine someday just for poops and giggles.
That said, it would be a completely different cam and intake design ... not to mention exhaust. As Rei said - his research is for V6/60 N/A.
Perhaps once he's 'done' aka 'gotten there' he can pick a new topic.

Lou I doubt Rae or myself will ever give up on GM 60 Degree V6 engines. When you get them right they are reliable and strong . It is a challanging and fun engine to work at perfecting and nobody ever said these engines were perfect from the factory!!! sleek

sleek,
By 'new topic' - I meant boosted v6/60. ;-)

Speaking of Eric, have you been watching what he's doing with roller lifters?
Speaking of weight... There are still BowTie blocks out there.  The factory bore size is small for you, though, and I'm not sure if the block can be sleeved larger while maintaining its strength
Edit: With a BowTie block and aluminum heads, you should be able to keep your car with a boosted 3.2 as light as your car with the naturally aspirated iron head/iron block combo [This message has been edited by Will (edited 09-08-2024).]
