You are going to piss people off with that 454 in a Mustang. Just Like I do with my F100 with 454.
Yeah...but hey, this is "hot rodding"...mixing matching/searching for used parts. I find that the journey of building a car is just as fun or maybe even more fun than driving it! Funny this is, LS-swapped Stangs are so common now that people don't even flinch!
So in the spirit of junkyard LS takes-outs, I'm trying a take-out 454 to see what happens. We'll call this the Ratstang.
Then why you askin'? "I'll take the 100CC Eddy's please. And a "cheap take out" 502 cam"."
Get to racing that ugly fckr!
Sometimes we answer our own questions...the Eddy's seem like the right head for what I need.
Vince, why not do a 502 instead of the 454? It would be king in that low rpm region.
Too dam expensive! This is strictly budget. I'm personally not into dropping 8-10k for an engine anymore. Ever since the junkyard turbo deal with my turbo Mustang, I feel the smiles-per-mile are much better with a good-running used motor that never had hands in it.
Yes it does. Do you genuinely want to build this engine yourself or are you more interested in the end result? I ask because you start with $2,100 heads, have the seats machined concentric with the guides, add roller rockers, custom length pushrods, custom cam, lifters, timing set, gaskets, head bolts, Perf RPM intake, tall valve covers, etc., and you're in the $4,000-$4,500 range. In comparison, $5,400 plus shipping gets you a completely refurbished Vortecpro 467 520 HP 560 Ft-lbs dyno tested with a warranty. Drop it in and turn the key.
Not building an engine. At this point, that ship has sailed for me. Picking up a 88k mile 7.4 Vortec, complete for $750.00 today. Will use a 502 cam or similar, factory lifters (what a cost saving there), and the standard issue RPM intake and Holley carb. While I agree Mark's engines are the real deal, the budget isn't there.
That article that Chris posted, for me, is an eye-opener. 560HP with a TFS heads. Just imagine that same engine with AFR heads and a better cam.
